基于先验目标分布的被动浮标阵布放半径分析

Passive Sonobuoy Array Deployment Radius Based on Transcendental Target Distribution

根据被动浮标阵应召搜潜过程,运用概率论和最优搜潜理论对浮标阵的布放半径进行研究。综合考虑浮标阵应召搜潜时潜艇初始位置、航速和航向等分布的特点,建立了浮标阵发现潜艇概率的数学模型,据此推导出使发现潜艇概率最大的布放半径(称之为改进的布放半径)。建立了反潜直升机布放典型浮标阵的搜潜模型,根据搜潜模型利用蒙特卡罗对搜潜效能进行仿真分析。结果表明:利用数学模型计算得到的发现潜艇概率与通过蒙特卡罗仿真得到的发现潜艇概率基本一致;与利用经典的布放半径布放浮标阵相比,利用改进的布放半径布放浮标阵能提高发现潜艇概率,且所需浮标数量少。

According to the procedure of on-call submarine search with passive sonobuoy arrays,the deployment radius was explored by using probability theory and optimal search theory.When using sonobuoy array for on-call submarine search,the distribution characteristics of the initial position,speed and course of the submarine was studied,the analytic model of search probability was obtained,and the deployment radius that has the maximum submarine search probability,called improved deployment radius,was derived based on the model.The submarine searching model of anti-submarine helicopter using typical dropped sonobuoy array was established,and the submarine search efficiency was analyzed with Monte Carlo simulation according to the model.The simulation results show that: 1) The search probability obtained by computation with the analytic model is basically identical to that of the Monte Carlo simulation;and 2) Compared with the sonobuoy array using conventional deployment radius,the sonobuoy array with the improved deployment radius has higher search probability and requires less quantity of sonobuoys.
