摘要: 为研究对抗条件下反潜助飞鱼雷的射击效率, 根据自航式声诱饵对抗下的反潜助飞鱼雷典型对潜作战过程, 建立了潜艇使用自航式声诱饵对抗鱼雷的对抗模型, 分析了反潜助飞鱼雷反对抗策略, 并以捕获概率作为射击效率的评定指标, 建立了基于蒙特卡罗法的射击效率模型, 通过仿真计算, 定量分析了射击距离、射击方式以及对抗因素对射击效率的影响。仿真结果表明, 射击效率随射击距离的增大而减小,采用对目标前置点射击方式可有效提升射击效率, 研究结论可为研究反潜助飞鱼雷作战使用方法和发挥其作战效能提供参考。Abstract: According to the typical anti-submarine operational process of a rocket assisted torpedo under mobile acoustic decoy countermeasure, a countermeasure model of a submarine using mobile acoustic decoy to counter an incoming torpedo is built, and the counter-countermeasure strategy of the rocket assisted torpedo is analyzed.Taking acquisition probability as an assessment specification of firing efficiency, a firing efficiency model is also built based on Monte Carlo method. Through simulation and calculation, the effects of firing distance, firing mode and countermeasure on the firing efficiency are quantitatively analyzed. Simulation results show that the firing efficiency decreases with the increase of firing distance, and the firing efficiency can be enhanced effectively by means of firing at the front point of a target. This work may provide a reference for studying operational application method of a rocket assisted torpedo and developing its operational effectiveness.
