The 2-D null preprocessing music algorithm for wide-band signals with uniform circular arrays
基于均匀圆阵的宽频段二维零点预处理MUSIC算法

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.
