| 1 | Chinese deserts and sand fields in Last Glacial Maximum and Holocene Optimum显示文摘The Last Glacial Maximum (LGM, c. 26-16 ka) and the Holocene Optimum (HO, c. 9-5 ka) were characterized by cold-dry and warm-wet climates respectively in the recently geological Earth. How Chinese deserts and sand fields responded to these distinctive climatic changes is still not clear, however. To reconstruct environments of the deserts and sand fields during the LGM and HO is helpful to understand the forcing mechanisms of environment change in this arid region, and to test paleoclimatic modeling results. Through our long-term field and laboratory investigations, 400 optically stimulated luminescence (OSL) ages and more than 100 depositional records in the Chinese deserts and sand fields were obtained; on the basis of these data, we reconstruct spatial distributions of the deserts and sand fields during the LGM and HO. Our results show that the sand fields of Mu Us, Hunshandake, Horqin and Hulun Buir in northern and northeastern China had expanded 25%, 37%, 38% and 270%, respectively, during the LGM; the sand fields of Gonghe in the northeastern Qinghai-Tibetan Plateau had expanded 20%, and the deserts of Badain Jaran, Tengger in central northern China had expanded 39% and 29% separately during the LGM; the deserts of Taklimakan, Gurbantünggüt and Kumtag in northwestern China had expanded 10%-20% respectively, compared to their modern areas. On the other hand, all of the sand fields were nearly completely covered by vegetation during the HO; the deserts in northwestern and central northern China were reduced by around 5%-20% in area during this time. Lakes in this arid region were probably expanded during the HO but this conclusion needs more investigation. Compared with the geological distributions of deserts and sand fields, human activity has clearly changed (expanded) the area of active sand dunes at the present time. Our observations show that environmental conditions of Chinese deserts and sand fields are controlled by regional climate together with human activity. | LU HuaYu YI ShuangWen XU ZhiWei ZHOU YaLi ZENG Lin ZHU FangYing FENG Han DONG LiNa ZHUO HaiXin YU KaiFeng MASON Joseph WANG XiaoYong CHEN YingYong LU Qi WU Bo DONG ZhiBao QU JianJun WANG XunMing GUO ZhengTang | 2013 | Chinese Science Bulletin2013，58，23： | 40 |
| 2 | Clinicopathologic characteristics and prognosis of gastroenteropancreatic neuroendocrine neoplasms: a multicenter study in South China显示文摘Background: Gastroenteropancreatic neuroendocrine neoplasms(GEP-NENs) are a heterogeneous group of rare tumors. Many issues in terms of epidemiologic features, pathogenesis, and treatment of GEP-NENs are still under discussion. Our study aimed to analyze the clinicopathologic characteristics and prognosis of Chinese patients with GEP-NENs.Methods: Complete clinicopathologic data and survival information of 1183 patients with GEP-NENs treated between 2005 and 2015 were collected from five medical centers in Guangdong Province, China. Patient survival was estimated using the Kaplan–Meier method and analyzed using the log-rank test; prognostic factors were analyzed using the Cox proportional hazards model.Results: The most common tumor location was the rectum(37.4%), followed by the pancreas(28.1%), stomach(20.7%), small intestine(7.2%), appendix(3.4%), and colon(3.3%). After initial definitive diagnosis, 1016(85.9%) patients underwent surgery. The 1-, 3-, and 5-year overall survival(OS) rates for the entire cohort were 87.9%, 78.5%, and 72.8%, respectively. The 3-year OS rates of patients with G1, G2, and G3 tumors were 93.1%, 82.7%, and 43.1%, respectively(P < 0.001). The 3-year OS rates of patients with stage I, II, III, and IV tumors were 96.0%, 87.3%, 64.0%, and 46.8%, respectively(P < 0.001). Patients with distant metastasis who underwent palliative surgery had a longer survival than those who did not(P = 0.003). Similar survival benefits of palliative surgery were observed in patients with neuroendocrine tumor(P y, M category, and sur= 0.031) or neuroendocrine carcinoma(P gery were found to be independent prog= 0.046). In multivariate analysis, age, grade, N categornostic factors.Conclusions: Patients with GEP-NENs who are women, younger than 50 years old, have smaller tumor size, have lower tumor grade, have lower T/N/M category, and who undergo surgery can have potentially longer survival time. Our data showed that surgery can improve the prognosis of GEP-NEN patients with distant metastasis. However, randomized controlled trials need to be conducted to establish the optimal criteria for selecting patients to undergo surgery. | Cheng Fang Wei Wang Yu Zhang Xingyu Feng Jian Sun Yujie Zeng Ye Chen Yong Li Minhu Chen Zhiwei Zhou Jie Chen | 2017 | Chinese Journal of Cancer2017，36，10： | 23 |
| 3 | Identification of coastal wetlands of international importance for waterbirds:a review of China Coastal Waterbird Surveys 2005–2013显示文摘Background:China's coastal wetlands belong to some of the most threatened ecosystems worldwide.The loss and degradation of these wetlands seriously threaten waterbirds that depend on wetlands.Methods:The China Coastal Waterbird Census was organized by volunteer birdwatchers in China's coastal region.Waterbirds were surveyed synchronously once every month at 14 sites,as well as irregularly at a further 18 sites,between September 2005 and December 2013.Results:A total of 75 species of waterbirds met the 1 % population level Ramsar listing criterion at least once at one site.The number of birds of the following species accounted for over 20 % of the total flyway populations at a single site:Mute Swan(Cygnus olor),Siberia Crane(Grus leucogeranus),Far Eastern Oystercatcher(Haematopus osculans),Bar-tailed Godwit(Limosa lapponica),Spotted Greenshank(Tringa guttifer),Great Knot(Calidris tenuirostris),Spoon-billed Sandpiper(Calidris pygmeus),Saunders' s Gull(Larus saundersi),Relict Gull(Larus relictus),Great Cormorant(Phalacrocorax carbo),Eurasian Spoonbill(Platalea leucorodia),Black-faced Spoonbill(Platalea minor) and Dalmatian Pelican(Pelecanus crispus).A total of 26 sites supported at least one species of which their number met the1 % criterion.Forty-two species met the 1 % criterion in the Yellow River Delta,Shandong;29 at the Cangzhou coast,Hebei and 26 species at the Lianyungang coast,Jiangsu.Conclusions:The results highlight the international importance of China's coastal wetlands for waterbirds.This study also demonstrates that participation of local birdwatchers in waterbird surveys results in data that are invaluable not only for understanding the current status of waterbirds in China's coastal regions but also for waterbird conservation and management. | Qingquan Bai Jianzhong Chen Zhihong Chen Guotai Dong Jiangtian Dong Wenxiao Dong Vivian Wing Kan Fu Yongxiang Han Gang Lu Jing Li Yang Liu Zhi Lin Derong Meng Jonathan Martinez Guanghui Ni Kai Shan Renjie Sun Suixing Tian Fengqin Wang Zhiwei Xu Yat-tung Yu Jin Yang Zhidong Yang Lin Zhang Ming Zhang Xiangwu Zeng | 2015 | Chinese Birds2015，，3： | 20 |
| 4 | Manipulation of Band Degeneracy and Lattice Strain for Extraordinary PbTe Thermoelectrics显示文摘Maximizing band degeneracy and minimizing phonon relaxation time are proven to be successful for advancing thermoelectrics.Alloying with monotellurides has been known to be an effective approach for converging the valence bands of PbTe for electronic improvements,while the lattice thermal conductivity of the materials remains available room for being further reduced.It is recently revealed that the broadening of phonon dispersion measures the strength of phonon scattering,and lattice dislocations are particularly effective sources for such broadening through lattice strain fluctuations.In this work,a fine control of MnTe and EuTe alloying enables a significant increase in density of electron states near the valence band edge of PbTe due to involvement of multiple transporting bands,while the creation of dense in-grain dislocations leads to an effective broadening in phonon dispersion for reduced phonon lifetime due to the large strain fluctuations of dislocations as confirmed by synchrotron X-ray diffraction.The synergy of both electronic and thermal improvements successfully leads the average thermoelectric figure of merit to be higher than that ever reported for p-type PbTe at working temperatures. | Yixuan Wu Pengfei Nan Zhiwei Chen Zezhu Zeng Siqi Lin Xinyue Zhang Hongliang Dong Zhiqiang Chen Hongkai Gu Wen Li Yue Chen Binghui Ge Yanzhong Pei | 2020 | Research2020，，1： | 6 |
| 5 | Simultaneous Detection and Removal of Formaldehyde at Room Temperature: Janus Au@ZnO@ZIF-8 Nanoparticles显示文摘The detection and removal of volatile organic compounds(VOCs) are of great importance to reduce the risk of indoor air quality concerns. This study reports the rational synthesis of a dual-functional Janus nanostructure and its feasibility for simultaneous detection and removal of VOCs.The Janus nanostructure was synthesized via an anisotropic growth method, composed of plasmonic nanoparticles,semiconductors, and metal organic frameworks(e.g.,Au@ZnO@ZIF-8). It exhibits excellent selective detection to formaldehyde(HCHO, as a representative VOC) at room temperature over a wide range of concentrations(from 0.25 to100 ppm), even in the presence of water and toluene molecules as interferences. In addition, HCHO was also found to be partially oxidized into non-toxic formic acid simultaneously with detection. The mechanism underlying this technology was unraveled by both experimental measurements and theoretical calculations: ZnO maintains the conductivity, while ZIF-8 improves the selective gas adsorption; the plasmonic effect of Au nanorods enhances the visible-light-driven photocatalysis of ZnO at room temperature. | Dawei Wang Zhiwei Li Jian Zhou Hong Fang Xiang He Puru Jena Jing-Bin Zeng Wei-Ning Wang | 2018 | Nano-Micro Letters2018，10，1： | 6 |
| 6 | Luminescent properties of Dy^3+/Eu^3+ doped fluorescent glass for white LED based on oxyfluoride matrix显示文摘Rare earth ion-doped fluorescent glass has become a hotspot due to its characteristics.This work shows that the prepared Dy^3+and Dy^3+/Eu^3+doped glasses have white light emission under ultraviolet excitation.There is a higher yellow light/blue light(Y/B)value,indicating an increase in the covalentity of Dy-O,and decrease in the symmetry with the increasing concentration of dopants(Dy^3+).The correlated color temperature(CCT)can be effectively reduced by the red light emission of Eu^3+,and the order of influence of excitation wavelength on CCT is 395 nm>382 nm>365 nm.The delay curve demonstrates the energy transfer from Dy^3+to Eu^3+.The glass has the characteristics of anti-blue light damage and wide tunable color temperature,which illustrates that it has potential application in the field of white LED. | Jingxi An Shuang Zhang Ruiwang Liu Guangxu Hu Zhiwei Zhang Yiyu Qiu Yanyan Zhou Fanming Zeng Zhongmin Su | 2021 | Journal of Rare Earths2021，39，1： | 5 |
| 7 | Design and experiment of a bionic vibratory subsoiler for banana fields in southern China显示文摘Subsoiling is essential in the tillage of banana planting,as banana plants have a fairly sturdy pseudostem and wide row spacing while soil tends to be compacted.In this study,a bionic vibrating subsoiler for banana fields was developed,verified,and evaluated.The vibrator was designed based on crank-rocker mechanism while the bionics design was used for subsoiler development.The forces on the susboiler were analyzed to verify the strength of the subsoiler tine.To test the performance of the subsoiler,field tests were conducted to measure the draft force and fuel consumption.There was approximately 14%reduction in the draft force and 22%increase in the fuel consumption in vibrating mode compared with that in non-vibrating mode.In conclusion,the study results could be applied in China’s tropical agricultural regions. | Zhang Xirui Wang Chao Chen Zhishui Zeng Zhiwei | 2016 | International Journal of Agricultural and Biological Engineering2016，9，6： | 4 |
| 8 | Ag@Au core/shell triangular nanoplates with dual enzyme-like properties for the colorimetric sensing of glucose显示文摘Due to the serious harm of diabetes to human health,development of sensitive assays for glucose level is of high significance for early prevention and treatment of diabetes.Currently,most conventional enzyme-based glucose sensors suffer from high cost and low stability due to the inherent defects of natural enzymes.Herein,we develop a pure nanozyme-based glucose detection method using Ag@Au core/shell triangular nanoplates(TNPs),which combines glucose oxidase(GOD)-and horseradish peroxidase(HRP)-like activities of the Au shell and inherent plasmonic properties of Ag TNPs.The sensing mechanism is based on the fact that the Au shell possessed GOD-like activity,enabling the oxidation of glucose to produce H2O2,which can further etch the silver core,leading to the decrease of absorbance at 800 nm and the color change from blue to colorless.Compared with the previous nanozymes-based glucose sensors,our method avoids the use of enzymes and organic chromogenic agent.Moreover,the stability of the Ag@Au core/shell TNPs is much better than that of Ag TNPs due to the protection by the coating of the Au shell.This method was successfully applied to the detection of urine samples from patients with diabetes,indicating its practical applicability for real sample analysis. | Ao Liu Mengmeng Li Jingxiang Wang Fan Feng Yu Zhang Zhiwei Qiu Yuzhu Chen Benjamin Edem Meteku Congying Wen Zifeng Yan Jingbin Zeng | 2020 | Chinese Chemical Letters2020，31，5： | 3 |
| 9 | Characteristics of SARS-CoV-2 Delta variant-infected individuals with intermittently positive retest viral RNA after discharge显示文摘SARS-CoV-2-infected patients will be discharged when viral ribonucleic acid(RNA)is consecutively negative at least twice over a 24-h interval.However,we have demonstrated that positive retest viral RNA,a particular clinical phenomenon initially observed in discharged SARS-CoV-2-infected patients in early 2020[1,2],is the occasional reoccurrence of Polymerase Chain Reaction(PCR)-detectable viral RNA but not reinfection[3]. | Lu Li Jingyan Tang Zhiwei Xie Qingxin Gan Guofang Tang Zhongwei Hu Huimin Zeng Jingrong Shi Jiaojiao Li Yan Li Changwen Ke Min Kang Dan Liang Huan Lu Yuwei Tong Xilong Deng Jinxin Liu Hongzhou Lu Fuxiang Wang Fengyu Hu Feng Li Nanshan Zhong Xiaoping Tang | 2022 | National Science Review2022，9，10： | 3 |
| 10 | Poisson's ratios and S-wave velocities of the Xishancun landslide,Sichuan,China,inferred from high-frequency receiver functions of local earthquakes显示文摘Landslides are recurrent geological phenomena on Earth that cause heavy casualties and property losses annually.In this study,we use the V_(p)-k stacking and nonlinear waveform inversion methods of high-frequency receiver functions extracted from local earthquakes,to sequentially invert Poisson’s ratios and S-wave velocities of the Quaternary Xishancun landslide,which is composed of three segments,i.e.,h1,h2,and h3 from bottom to top.Our results show that Poisson’s ratio values are generally higher than 0.33 and that the S-wave velocities vary from 0.1 to 0.9 km s^(-1).High Poisson’s ratios(>0.44)are mainly distributed in the juncture regions between different segments,as well as the western edge of h2.These zones show significant variation in landslide thickness and are potentially hazardous areas.Low velocities of 0.05–0.2 km s^(-1)with thicknesses of 10–30m are widely observed in the lower layer of the landslide.The high Poisson’s ratios and low-velocity layer may be related to water-rich materials in these areas.Our study suggests that the high-frequency receiver functions from local earthquakes can be used to delineate geotechnical structures,which is valuable for landslide stability analysis and hazard mitigation. | Zigen WEI Risheng CHU Zhiwei LI Minhan SHENG Qiu ZENG | 2021 | Science China Earth Sciences2021，64，7： | 3 |
| 11 | Molecular Clump Extraction Algorithm Based on Local Density Clustering显示文摘The detection and parameterization of molecular clumps are the first step in studying them.We propose a method based on the Local Density Clustering algorithm while physical parameters of those clumps are measured using the Multiple Gaussian Model algorithm.One advantage of applying the Local Density Clustering to the clump detection and segmentation,is the high accuracy under different signal-to-noise levels.The Multiple Gaussian Model is able to deal with overlapping clumps whose parameters can reliably be derived.Using simulation and synthetic data,we have verified that the proposed algorithm could accurately characterize the morphology and flux of molecular clumps.The total flux recovery rate in 13CO(J=1-0)line of M16 is measured as 90.2%.The detection rate and the completeness limit are 81.7%and 20 K km s-1 in 13CO(J=1-0)line of M16,respectively. | Xiaoyu Luo Sheng Zheng Yao Huang Shuguang Zeng Xiangyun Zeng Zhibo Jiang Zhiwei Chen | 2022 | Research in Astronomy and Astrophysics2022，22，1： | 3 |
| 12 | Osteopontin inhibits osteoarthritis progression via the OPN/CD44/PI3K signal axis显示文摘Chondrocyte degeneration and extracellular matrix component loss are the primary causes of osteoarthritis(OA).OA can be treated by inhibiting chondrocyte degeneration and increasing extracellular matrix component secretion.Osteopontin(OPN),a multifunctional protein,has gained immense attention with regard to its involvement in OA.This study aimed to explore the therapeutic value and mechanism of action of OPN in OA treatment.Results of the histomorphological analysis revealed a worn-off OA cartilage tissue surface,cartilage matrix layer deterioration,and calcium salt deposition.Compared to that in normal chondrocytes,in OA chondrocytes,the OPN,CD44,and PI3K protein and mRNA expression was upregulated.Further,siOPN,rhOPN,and rhOPN plus LS-C179404 interfered with OA chondrocytes.As verified in mice,OPN directly inhibited the expression level of PI3K in OA chondrocytes by binding with CD44.Morphological analysis of the knee joints demonstrated that OPN effectively inhibited OA progression via the OPN/CD44/PI3K signal axis.In conclusion,OPN activates intracellular PI3K signaling molecules by binding to CD44 on the cell surface to cause downstream cascading effects,thereby delaying chondrocyte degeneration and reducing cartilage matrix component loss;therefore,OPN is a potential therapeutic agent for OA. | Qing Liu Hao Zeng Yuhao Yuan Zhiwei Wang Ziyi Wu Wei Luo | 2022 | Genes & Diseases2022，9，1： | 2 |
| 13 | Spatial patterns of urban green space and its actual utilization status in China based on big data analysis显示文摘Urban green space(UGS)is essential for sustainable urbanization and human well-being.The utilization status of UGS is closely related to the provision of ecosystem services for urban residents.Limitations on data availability,however,have led to the absence of a comprehensive approach for evaluating the actual utilization status of UGS at a large scale.Furthermore,differences in actual UGS utilization between intra-urban and peri-urban areas have not received enough attention.This study used big data analysis by combining point of interest(POI)and land use and cover change(LUCC)to quantify the spatial patterns of UGS utilization,and to evaluate the actual utilization status of UGS in 366 cities on the Chinese mainland.We also explored the differences in the actual utilization of UGS in intra-urban and peri-urban areas.The results showed that 94.01%of UGS resources in China had not been utilized.There was a clear pattern of spatial mismatch between the stock and the actual utilization of UGS,especially in the north-western region indicated by the Hu Huanyong Line.The actual utilization rate of UGS was closely related to the regional develop-ment level.There was a certain mismatch between the actual utilization and stock of intraurban green space(IUGS).The hot spots of the actual utilization rate of IUGS were in Yunnan,Guizhou,and Sichuan Provinces in southwestern China.The differ-ences in UGS actual utilization rates between IUGS and peri-urban green space(PUGS)were small in eastern China,but large in south-western and northwestern China.The actual utilization rate of IUGS in most Chinese cities was significantly larger than that of PUGS,indicating that PUGS were not well utilized.Our results provide scientific support for urban and regional planners in targeting specific areas for UGS design and development,and in optimizing future UGS planning in China. | Yiyi Huang Tao Lin Guoqin Zhang Yongguan Zhu Zhiwei Zeng Hong Ye | 2021 | Big Earth Data2021，5，3： | 2 |
| 14 | The Effects of Polyphenol Oxidase and Cycloheximide on the Early Stage of Browning in Phalaenopsis Explants显示文摘Explant browning is one of the major problems in the tissue culture process, and polyphenol oxidase(PPO), is the major proteases involved in plant tissue browning. We investigated the effects of polyphenol oxidase on the early stage of browning in explants of the orchid Phalaenopsis. Our results show that PPO activity was significantly higher in explants cultured for 3 d than in the 0 h control. The levels of PPO transcripts and PPO protein were significantly higher in explants cultured for 6 h compared to the 0 h control; these high expression levels were maintained over increasing cultivation time. Cycloheximide(CHX) treatment reduced PPO transcript levels, PPO protein levels, and PPO enzyme activity. High levels of PPO m RNA and PPO protein were detected in the cytoplasm and vascular bundles of Phalaenopsis explants cultured for 6 h compared to explants cultured for 0 h, 24 h, and 3 d. CHX treatment did not significantly affect the distribution of PPO m RNA and PPO protein in explant tissues, but their levels were significantly lower than those of the untreated control. | XU Chuanjun RU Zhiwei LI Ling ZENG Biyu HUANG Junmei HUANG Wen HU Ou | 2015 | Horticultural Plant Journal2015，1，3： | 2 |

| 16 | Characteristics of Eddy Current Attenuation and Thickness Measurement of Metallic Plate显示文摘In eddy current testing, the law of attenuation of eddy current(EC) is of great concern. In conductive half space under the excitation of uniform magnetic field, the EC density decreases exponentially in the depth direction. However, in conductor with finite thickness tested by coil, the distribution of EC in the depth direction is more complicated. This paper studies the characteristics of EC attenuation in metallic plate of finite thickness. Simulation results show that there is an EC reflection at the bottom of plate, which changes the law of EC attenuation. A new concept, namely the equivalent attenuation coefficient, is proposed to quantify the speed of EC attenuation. The characteristics of EC attenuation are utilized to explain the nonmonotonic relation between coil voltage and plate thickness. Procedure of selecting frequency is discussed. Thereafter, measurement of plate thickness is carried out and accurate result is obtained. | Zhiwei Zeng Pengcheng Ding Jiayi Li Shaoni Jiao Junming Lin Yonghong Dai | 2019 | Chinese Journal of Mechanical Engineering2019，32，6： | 2 |
| 17 | Histones released by NETosis enhance the infectivity of SARS-CoV-2 by bridging the spike protein subunit 2 and sialic acid on host cells显示文摘Neutrophil extracellular traps(NETs)can capture and kill viruses,such as influenza viruses,human immunodeficiency virus(HIV),and respiratory syncytial virus(RSV),thus contributing to host defense.Contrary to our expectation,we show here that the histones released by NETosis enhance the infectivity of SARS-CoV-2,as found by using live SARS-CoV-2 and two pseudovirus systems as well as a mouse model.The histone H3 or H4 selectively binds to subunit 2 of the spike(S)protein,as shown by a biochemical binding assay,surface plasmon resonance and binding energy calculation as well as the construction of a mutant S protein by replacing four acidic amino acids.Sialic acid on the host cell surface is the key molecule to which histones bridge subunit 2 of the S protein.Moreover,histones enhance cell-cell fusion.Finally,treatment with an inhibitor of NETosis,histone H3 or H4,or sialic acid notably affected the levels of sgRNA copies and the number of apoptotic cells in a mouse model.These findings suggest that SARS-CoV-2 could hijack histones from neutrophil NETosis to promote its host cell attachment and entry process and may be important in exploring pathogenesis and possible strategies to develop new effective therapies for COVID-19. | Weiqi Hong Jingyun Yang Jun Zou Zhenfei Bi Cai He Hong Lei Xuemei He Xue Li Aqu Alu Wenyan Ren Zeng Wang Xiaohua Jiang Kunhong Zhong Guowen Jia Yun Yang Wenhai Yu Qing Huang Mengli Yang Yanan Zhou Yuan Zhao Dexuan Kuang Junbin Wang Haixuan Wang Siyuan Chen Min Luo Ziqi Zhang Tiangi Lu Li Chen Haiying Que Zhiyao He Qiu Sun Wei Wang Guobo Shen Guangwen Lu Zhiwei Zhao Li Yang Jinliang Yang Zhenling Wang Jiong Li Xiangrong Song Lunzhi Dai Chong Chen Jia Geng Maling Gou Lu Chen Haohao Dong Yong Peng Canhua Huang Zhiyong Qian Wei Cheng Changfa Fan Yuquan Wei Zhaoming Su Aiping Tong Shuaiyao Lu Xiaozhong Peng Xiawei Wei | 2022 | Cellular & Molecular Immunology2022，19，5： | 2 |
| 18 | Target location with signal fitting and sub-aperture tracking for airborne multi-channel radar显示文摘The location of a moving target based on signal fitting and sub-aperture tracking from an airborne multi-channel radar is dealt with.The proposed approach is applied in two steps:first,the ambiguous slant-range velocity is derived with a modified single-snapshot multiple direction of arrival estimation method,and second,the unambiguous slant-range velocity is found using a track-based criterion.The prominent advantage of the proposed approach is that the unambiguous slant-range velocity can be very large.Besides,the first stage is carried out at the determinate range-Doppler test cell by azimuth searching for fitting best to the moving target signal,therefore,the location performance would not be sacrificed in order to suppress clutter and/or interference.The effectiveness and efficiency of the proposed method are validated with a set of airborne experimental data. | Zhiwei Yang Guisheng Liao Shun He Cao Zeng | 2010 | Journal of Systems Engineering and Electronics2010，21，5： | 2 |
