摘要

本文首先给出了波达方向估计最大似然函数的方差，根据此方差导出了最大似然方向估计的信噪比分辨门限公式，并根据这一公式分析了两信源相关特性不同时的最大似然算法的信噪比分辨门限。

Abstract

The variance of maximum likelihood function of DOA（Direction of Arrival）is derived.According to the relation

the SNR resolution threashold formula of maximum likelihood estimation of DOA is deduced.from which the SNR resolution threshold is analyzed for two sources of different correlativity with the application of uniformly spaced linear array.
