摘　　要：对于小型主动探测装置在混响背景干扰下的目标探测制导问题，研究了一种简单且易于工程实现的目标探测方法。在深人研究水中目标探测系统的工作背景特点基础上，结合目标回波识别和制导方位估计技术，设计了一种混响背景干扰下方法的目标探测方法。仿真和试验结果表明：所设计的方法运算简单实时性高，能很好地给出制导方位信息，探测到水中目标。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 pa- per. 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.
