摘要

本文针对相干源的DOA估计问题

利用最大特征值对应的特征矢量(简记为最大特征矢量)

提出了一种新的Toeplitz去相干方法.该方法用最大特征矢量构造了一个Toeplitz矩阵来估计相干源的波达方向

实现简单

不损失阵列孔径.相对于常规的去相干算法具有更好的估计性能

特别是在低信噪比情况下

且能估计更多相干源.理论分析和仿真结果均验证了该方法的有效性.

Abstract

A Toeplitz decorrelation method using the eigenvector corresponding to the maximum eigenvalue (simplified as the maximum eigenvector) is proposed for the DOAs estimation of coherent sources.This method uses the largest eigenvector to construct a new Toeplitz matrix to estimate DOAs of coherent sources.Compared with the conventional decorrelation methods

it has better estimation performance

especially at low SNR scenarios

and it can estimate more coherent sources.Theoretical analyses and simulation results both show that the presented method is effective.
