Abstract

Focused on the reverberation interference problem in active sonar detective system, a brief and effective underwater target detective method was designed. The fundamental principle of an underwater target detective system is deeply researched in this paper. And then, the recognition of target echo and estimation of the direction of arrival signals (DOA) under the strong reverberation environment are used to design the detective method. The simulation results of the system detection probability are given. It is proved that the detective system researched in this paper can detective the underwater target well.

Key words： constant false alarm rate (CFAR); detection performance; reverberation; SRR
