摘要

针对GPS信号的DOA难以获得的问题,利用本地信号和接收信号构造了两种形式的互相关矩阵及其综合形式,根据本地信号导向矢量与互相关矩阵的特征结构之间的关系,通过迭代运算得到了GPS信号的DOA。实验结果表明,该方法的运算过程简单而且GPS信号的DOA估计值精度较高。

关键词： GPS信号; 导向矢量; 互相关矩阵; DOA; 迭代运算

Abstract

Aim at the problem of bing difficult to obtain DOA of GPS signal, two kinds of correlation matrix and corresponding compositive forms are built by use of both local and received signals, according to the relationship of steering vector of local signal and characteristic of correlation matrix, DOA of GPS signal is got by means of iterative operations. Experiment shows that the method is simple in course of operating and the precision of DOA estimated value of GPS is superior.

Key words： GPS signal; steering vector; correlation matrix; DOA; iterative operation
