摘要

本文概述了MUSIC算法

当阵元间距不大于载波半波长时

通过分析得出MUSIC算法空间分辨率随阵元间距增大而提高

并推导阵元间距与MUSIC算法性能的定量关系;当阵元间距大于载波半波长时

讨论空间谱可能出现虚假谱峰的情况

并提出提取真实谱峰的方案.最后通过计算机模拟仿真验证文中结论.

Abstract

Based on summarizing MUSIC algorithm

the quantitative relationship

that the performance of MUSIC algorithm gets better while array elements spacing becomes longer

was analyzed under the condition of array elements spacing not larger than half wavelength of carrier;the possible occurrence of false peaks was discussed as array elements spacing was larger than half wavelength of carrier

and one solution to pick up true peaks was provided.At last

the conclusions in this paper are verified by simulation experiments.
