摘要

基于信号子空间的超分辨方法一般对接收器阵列误差非常敏感。本文提出的投影变换法利用目标方向的初始估计和阵列流形的先验知识，可以显著减小信号子空间方法的误差灵敏度。文中给出了数值仿真和实际阵列数据测试的结果。

Abstract

Signal subspace-based high resolution algorithms are usually sensitive to various uncertainties such as locations errors

amplitude and phase errors in the receivers etc.It is demonstrated in this correspondence that the signal subspace method sensitivity can be significantly decreased by utilizing preliminary emitter direction estimates and a priori knowledge regarding the array geometry with a projection operator.Numerical results are also presented.
