摘要

本文给出了基于Gram-Schmidt正交化方法的超分辨算法

并分析了该算法对阵列幅度和相位误差的灵敏度.给出了两个目标、不同阵元数和不同阵元间距等情况下的灵敏度计算结果。结果表明

本文的算法在目标小角度间隔、大阵元数的情况下

受幅相误差的影响没有最大似然估计（MLM）和MUSIC算法敏感。

Abstract

This paper presents a superresolution algorithm. n the Gram-Schmidtorthogonality method

analyzes the sensitivity of the direction-of-arrival （DOA） of the algorithm to the gain and phase errors

and gives the numerical results of the sensitivity related with different number of elements and different element spacing about two sources. The results show that the algorithm in this paper is more insensitive to the gain and phase errors than the Maximum Likelihood Method （MLM） and MUSIC method in condition of small seperating angle and large number of elements.
