基于舰壳声纳的多舰协同检查搜潜建模与仿真

基于舰载舰壳声纳搜潜原理及舰艇协同检查搜潜战术，分别建立了在潜艇初始位置、航向及航速未知条件下，舰壳声纳对潜艇目标的矩形、扩展方形及包围方形检查搜索的数学模型；基于已建搜索模型及假定的潜艇运动模型，利用蒙特卡洛方法，得到了相同仿真条件下3种搜索算法的搜潜概率及搜到潜艇所需平均时间，三种算法的搜潜概率与潜艇初始航向角、潜艇航速、潜艇航向变化次数等潜艇运动因素之间的关系，并对搜潜概率及搜潜时间进行了分析比较，获得了有益的效果。

Modeling and Simulation of Multi-Ship Cooperative Inspection Submarine-Search Based on Ship-Shell Sonar

Based on search theory of ship-borne shell sonar and ship cooperative inspection search tactics, mathematical models of rectangle, extending square and surrounding square search for submarine using ship-shell sonar were built under the unknown submarine initial position, course and velocity. On the basis of search models built and assumed submarine movement models, search probability and mean time of three search algorithms under the same simulation conditions, and the relationship between search probability of three algorithms and submarine movement factors such as submarine initial course, submarine velocity and submarine course change times, etc. were attained using Monte Carlo method. Search probability and time were analyzed and compared of three algorithms, and effective results were gotten.
