基于均匀圆阵的宽频段二维零点预处理MUSIC算法

THE 2-D NULL PREPROCESSING MUSIC ALGORITHM FOR WIDE-BAND SIGNALS WITH UNIFORM CIRCULAR ARRAYS

该文基于多圈均匀圆阵(UCA),在UCA-RB-MUSIC算法(Mathews等,1994)和一维零点预处理算法(魏平等人,1996)的基础上,提出了一种可任意设置响应零点的宽频段二维MUSIC算法,计算机仿真表明,该方法在保持了UCA-RB-MUSIC算法的高精度、高分辨力和降低了运算量的前提下,在宽频段内对于空间干扰信号的抑制有较好的效果。

Based on UCA-RB-MUSIC algorithm(Mathews, et al., 1994) and 1-D null preprocessing algorithm (Wei Ping, et al, 1996), a 2-D UCA MUSIC algorithm for wide-band sources with arbitrary spatial null response is presented. The computer simulations indicate that the spatial wide-band interference can be suppressed exactly, the high precision and high resolution of UCA-RB-MUSIC algorithm is maintained, and the computational burden is reduced.
