| 摘 要： | 本文基于自适应天线系统中的辨识信号到达方向AOA(Angle of Arrival)关键问题,研究了其实现的MUSIC算法的原理,并通过MATLAB仿真分析,结果表明,接收信号个数必须小于阵元数才能用MUSIC算法进行波达方估计,MUSIC算法对于波达方向估计的分辨率在接近90°处为5°左右,在接近0°~180°处为5°~7°。

| Abstract: | The key issue of the adaptive antenna system is the identification of Angle of Arrival(AOA).Based on this,the paper Focus on the realization of the principle of the MUSIC algorithm and get two conclusions through MATLAB analysis.First,MUSIC algorithm can be used to estimate DOA,only when the number of the Received signal is less than array elements.Second,the resolution of MUSIC algorithm for DOA estimation is about 5 degrees at close to 90 degrees of DOA,and is about 5 to 7 degrees at close to 0 or 180 degrees of DOA. |
