Abstract

A tank experiment on direct blast suppression (DBS) in bistatic sonar was conducted in Harbin Engineering University. Two algorithms were compared in data processing. The first one is jamming matrix algorithm and the second one is nulls constraint matrix algorithm. Both algorithms need the prior information of the direction of arrival (DOA) of direct blast (DB). Experimental results indicate that the latter algorithm has the better performance and can derive a higher output signal-to-noise ratio (SNR) with the same data. However, the former algorithm can preserve the time domain information of the signal.
