Abstract

Abstract

Based on time-space processing, a 2-D array extension method is introduced to investigate the virtual geometry of array and construct its pseudodata matrix. Meanwhile, an algorithm is presented for suppression of same-frequency interference. The equivalent array aperture of the methods is (m+1)2/2-1 (when m is odd) or m(m+2)/2-1 (when m is even) with m-sensors. The method and the algorithm can work under lower SNR (0dB), and the 2-D parameters can be automatically paired. Theoretical analysis and computer simulations show the effectiveness of the array extension and the algorithm.
