水雷战对探雷率要求极高，海军在传统反水雷作战中采用了多种探雷技术和方 法。不是专为反水雷而开发的激光探雷方法可精确地探测、识别和定位水下环境中的水雷和小 目标，本文介绍了机载激光测深原理、光达探雷技术，并说明了国外的几型激光测深装置及其 探雷效果。 Mine warfare has a very high demand for mine detection, and the Navy has employed a variety of mine detection techniques and methods in traditional counter-mine operations. Laser mine detection method, which is not designed for anti-mine operation, can accurately detect, identify and locate underwater mines and small targets in underwater environment. This paper introduces the principle of airborne laser sounding, Several types of laser sounding device and mine detection effect.
