摘　　要：对于空投浮标、鱼雷等反潜武器的入水瞬态信号进行检测一直是水声对抗领域的一项关键技术。本文针对入水瞬态信号介绍了4种常用的统计量检测方法,并通过蒙特卡洛仿真和湖试数据处理比较了4种检测方法的检测效果,分析了各自的特点,对水声瞬态信号检测具体工程应用具有较好的参考价值。The detection of the transient signals of anti-submarine weapons into the water,such as air-dropped buoys and torpedoes,is the key to underwater acoustic countermeasures.In this paper,four commonly used statistical detection methods for the transient signals are introduced and their detection effects through Monte Carlo simulation and lake trial data processing are compared,also their respective characteristics are analyzed.This study provides a good reference for specific engineering application of underwater acoustic transient signal detection.
