In order to realize the improved TS-ESPRIT, the proposed algorithm divides the planar array into multiple uniform sub-planar arrays with common reference point to get a unified phase shifts measurement point for all sub-arrays. The TS-ESPRIT is applied to each sub-array separately, and in the same time with the others to realize the parallelly temporal and spatial processing, so that it reduces the non-linearity effect of model and decreases the computational time. Then, the time difference of arrival(TDOA)technique is applied to combine the multiple sub-arrays in order to form the improved TS-ESPRIT. It is found that the proposed method achieves high accuracy at a low signal to noise ratio(SNR)with low computational complexity, leading to enhancement of the estimators performance. 关 键 词：direction of ARRIVAL estimation (DOAE) temporal SUBSPACE spatial SUBSPACE estimating signal parameters via rotational INVARIANCE technique (ESPRIT)
