摘　　要：物体入水声是一种随机出现的瞬态信号,分析了物体落水声特性,提出了利用声学浮标系统测量物体落水点位置的方法,在此基础上论述了声学浮标探测作用距离预报方法,介绍了纯方位法测量目标位置的基本原理和方法,对测量误差来源进行了理论推导,并进行了误差仿真分析,可为类似系统设计提供参考。The splash of target＇ s water entry is an instantaneous signal. The characteristic of splash sound for target＇ s water entry is analyzed. The method of measuring water entry point by using acoustics buoy is presented. On this basis, the method of forecasting detection range is discussed, the principle and method for measure the target＇ s position by bearing-only are introduced, and the position error is simulated and analyzed. This method could provide reference for the further study of same system.
