摘　　要：由于矢量水听器和声压水听器能够分别拾取声场中的振速及声压信息,因此两者组成的单矢量声压水听器就可以实现目标方位的估计。介绍了方位估计方法中的柱状图法,详细介绍了该方法的原理,并通过对单矢量声压水听器海试结果的处理和分析,验证了该方法在目标方位估计及多目标识别上的有效性。As vector hydrophone and sound pressure hydrophone can separately pick up vibration velocity and sound pressure in the sound field,the single vector and sound pressure hydrophone composed of both above hydrophones can achieve target DOA estimation. The histogram method among DOA estimation methods is introduced,the theory of this method is also introduced in detail. By processing and analyzing the ocean test results of single vector and sound pressure hydrophone,the validity of this method on target DOA estimation and multi-target identification is verified.
