摘要: 舰艇如何优化布放悬浮式声诱饵和悬浮式深弹阵防御声自导鱼雷是舰艇防御鱼雷攻击的重要问题之一。本文建立了舰艇使用悬浮式声诱饵与悬浮式深弹阵对抗鱼雷的作战模型, 采用极值法和非线性规划方法, 确定了悬浮式声诱饵与悬浮式深弹阵的发射策略及舰艇的规避航向, 使舰艇布放悬浮式声诱饵与悬浮式深弹阵和正确的规避机动有效结合, 以期达到对抗来袭鱼雷的最佳效果。仿真结果表明, 采用本文方法可以达到软硬防御手段有效结合对抗来袭鱼雷的双重效果, 鱼雷拦截概率提高了10%~30%。Abstract: Properly deploying hovering acoustic decoy and hovering depth charge array to counter acoustic homing torpedo is of great importance for a surface ship. This paper establishes an operational model of ship countering torpedo with hovering acoustic decoy and hovering depth charge array, defines the launch strategy of hovering acoustic decoy and hovering depth charge array and the evading course of surface ship by using extremum method and the non-linear planning method, and effectively combines the deploying of decoy and depth charge array with the evasive maneuver to achieve the best countering effect. Simulation results show that the proposed method can effectively counter coming torpedo by combining the soft-kill and hard-kill anti-torpedo measures, and enhance the probability of intercepting torpedo by 10% ~30%.
