摘要

本文提出阵列测向中基于零点设计的预处理方法，然后采用最优分辨门限准则和估计方差下限不变准则对这一预处理方法进行了性能分析，证明适当设计的零点预处理算法的性能是最优化的．最后，模拟实验和系统场地实验数据举例验证了该方法在相干来波方向估计中的应用．

Abstract

A spatial null preprocessing algorithm is proposed

and it’s performance according to the criteria of the optimal resolution and Cramer-Rao lower bound has been studied. The method presented here and it’s application to the direction of arrival estimation with coherent sources are varified by the simulation results and experiments using real-world data.
