Modeling and Simulation of Dipping Sonar Submarine Search Efficiency

摘要:

基于反潜直升机吊放声纳的探测原理及战术使用特点,在目标初始位置概略已知,速度和航向未知的条件下,分析了目标散布规律,建立了搜潜效能分析计算模型,给出了吊放声纳在扩展方形搜索方式下的应召搜潜概率；并采用蒙特卡洛法的基本思想对该计算模型进行了仿真验证,证明了该方法的有效性；最后,基于扩展方形搜索方式,研究了在单机和双机搜潜条件下搜索概率的不同结果,分析了潜艇速度、应召延迟时间、吊放次数等参数 对搜索概率的影响。

Abstract:

Based on the detection theory and tactical use characteristic of ASW helicopter dipping sonar, a target scattermodel was analyzed on the condition of known target initial position, unknown course and speed of submarine, followingsearch efficiency model was built. Then searching for submarine probability was provided based on the extended squaresearch mode, meanwhile the model was validated by the Monte Carlo method , which proved the effectiveness of the meth.od. At last based on extended square search mode, different search probability was given in the case of single aircraft anddual aircraft search, then the influence of submarine velocity was , the time of submarine lose contact and the times of dip.ping was analyzed on search probability.
