Operational Model for Intercepting Uncertain Type of Torpedo with Hovering Depth Charge
-
摘要: 水面舰艇如何使用悬浮式深弹拦截鱼雷是舰艇防御鱼雷的重要问题之一。该文通过利用模糊数学知识将鱼雷报警距离分为近、中、远3个模糊区域, 建立了鱼雷报警距离隶属函数关系, 预估了鱼雷目标航向、航速等运动要素, 最后建立了悬浮式深弹拦截不确定型鱼雷作战模型, 并对作战模型进行了计算机仿真。仿真结果表明, 舰艇在不能确定来袭鱼雷型号和自导方式时, 选择使用悬浮式深弹这一硬杀伤方式拦截鱼雷是最为可行的方案, 能够达到彻底毁伤鱼雷, 从而保护舰艇安全的最终目的。Abstract: How to use hovering depth charge to intercept torpedo is one of the main problems in surface ship torpedo defense. Fuzzy mathematics knowledge is used in this paper for dividing a torpedo warning distance into near, middle, and far fields to establish torpedo warning distance functions and estimate torpedo course and speed. Hence, an opera-tional model for surface ship to intercept uncertain type of torpedo with hovering depth charge is constructed. Simulation via the Monte-Carlo method is performed, and the result shows that intercepting uncertain type of torpedo with hovering depth charge is the most available measure, which can achieve the purpose of completely damaging the torpedo and ensuring the safety of surface ship.
