| 1 | Wigner Frequency Point Slice Analysis of Superposition Data for Phased-Array Ground Penetrating Radar显示文摘According to the frequency property of Phased-array ground penetrating radar (PGPR), this paper gives a frequency point slice method based on Wigner time-frequency analysis. This method solves the problem of analysis for the PGPR’s superposition data and makes detecting outcome simpler and detecting target more recognizable. At last, the analytical results of road test data of the Three Gorges prove the analytical method efficient. | ZOULian CHENShu-zhen YANGShen WEIDan XIAOBo-xun | 2004 | Wuhan University Journal of Natural Sciences2004，9，6： | 2 |
| 2 | Application of Two Migration Methods for Ground Penetrating Radar Data显示文摘This paper begins with the basic principles of finite-difference migration and diffraction scan migration, and then compares the processing results of the practical ground penetrating radar GPR data with these two migration methods. It is illustrated that migration can refocus the reflecting points in radar record to their true spatial location and provide the foundation for interpretation, thus improving precision of interpretation of (GPR) profiles. | ShiJing ChenShu-zhen ZouLian XiaoBo-xun | 2004 | Wuhan University Journal of Natural Sciences2004，9，2： | 1 |
| 3 | Research on Data Combination for Phased-Array Ground Penetrating Radar显示文摘To resolve the data combination of Phased-array Ground Penetrating Radar (PAGPR), we first build a model of PAGPR and a layered model, and then a new data combination algorithm is presented based on it. This method calculates time delay of multi-receivers, basing on the signal of the nearest receiver, then shifts other signals and adds them up, and gets one signal at last. It has been proved that this method can restrain noise, multiple waves, clutter waves and improve the precision of time location. In the end, an example is given to prove the method’s efficiency. | ZouLian ChenShu-zhen ShiJing XiaoBo-xun | 2003 | Wuhan University Journal of Natural Sciences2003，8，04A： | 1 |
