MUSIC算法中信源个数和多峰参数的自动判读探索

utomatic Reading of Source Numbers and Multiple Peak Parameters by MUSIC Algorithm

中文摘要英文摘要

一个智能天线系统需要自动同时处理来自不同方向的多个信号源的能力。本文利用Matlab进行Music空间谱仿真分析,在研究不同到达角处角度分辨率基础上,在均匀线阵天线条件下成功探索了自动判读多信号源个数和到达角的方法。依据角度分辨率试验成功实现了"削峰"和下一个谱峰的分析。依据线阵对到达角的敏感性,虚拟"倒序并列"均匀线阵,采用"共轭倒序平均法"成功改善了对空间谱的分辨能力。

A smart antenna system needs to process signal sources from different directions spontaneously. With MATLAB simulation experiments on spatial spectrum analysis by MUSIC algorithm , automatic reading of source numbers and multiple peak parameters is successful on basis of resolution tests for different DOAs. This paper also demonstrates a "cutting-peak" method to process "the next spectrum peak", as well as the "conjugate reverse average" method to improve the resolving abilibty of spatial spectrum.
