探雷声纳有效搜索带仿真研究

摘要

针对舰艇摇摆下,探雷声纳有效搜索带难以确定的问题,运用舰艇摇摆模型和声纳三维多波束模型研究确定探雷声纳有效搜索带的方法.给出了探雷声纳有效搜索带的定义,提出了一种基于海底网格划分定量仿真计算探雷声纳有效搜索带的方法.给定探测海域海洋环境参数和声纳各工作参数,运用该方法即可确定有效搜索带的宽度和位置.仿真结果表明,该方法简便有效、计算结果正确,可为探雷声纳的作战使用提供重要依据.%The valid search strip of Mine Detecting Sonar can't be exactly estimated when ship is swayed, the valid search strip of mine detecting sonar by established ship sway model and 3-D beams models have been studied. A method for quantificational simulate the valid search strip of mine detecting sonar is proposed by carving up gridding to the sea bottom after giving the definition. The width and position of valid search strip can be calculated if the sea environment parameter and the sonar working parameter are known. The method is simple, efficiency,and the calculate result is correct.This method can offers according to the campaign use of mine detecting sonar.
