摘　　要：为了研究鱼雷声自导性能,有必要对自导系统检测概率进行分析。从自导接收机信号处理方式、检测概率与检测阈的关系出发,提出了基于信号余量的被动声自导检测概率计算方法。仿真结果表明,鱼雷声自导系统被动检测概率在距离上成三种分布。在一定距离内,检测概率均超过0.5;在远距离上仅有极个别深度可检测到潜艇目标;在前两者之间,检测概率受深度影响较大,因此有必要进行深度上的优化选择。In order to research performance of torpedo acoustic homing system, it＇ s necessary to analyze system detection probability. Ac-cording to acoustic homing system signal processing method and the relation between detection probability and detection threshold, detection probability was calculated through signal excess simulation. The results indicate that detection probability has 3 kinds of distribute at differ- ent distance. In short range, detection probability is higher than 0. 5. In long range, submarine can be detected on few depths. Between the former ones, the effect of depth is powerful and it＇ s essential to design torpedo navigating depth.
