火箭助飞式声干扰器和悬浮式深弹协同对抗线导鱼雷建模与仿真

Modeling and Simulation of Cooperative Defense Against Wire-guided Torpedo with Rocket Assisted Noise-jammer and Hovering Depth Charge

提出了使用火箭助飞式声干扰器和悬浮式深弹组合协同防御潜射线导鱼雷战术，根据线导鱼雷射击原理，仿真估算了导引艇的舷角，建立了火箭助飞式声干扰器和悬浮式深弹这一软硬反鱼雷武器组合协同防御潜射线导鱼雷的数学模型，利用运筹学中的优化方法确定了两型武器的布放策略及舰艇的规避航向，并对使用软硬武器协同对抗与单一软对抗的对抗成功概率进行了仿真比较，结果表明，使用软硬武器协同对抗效果显著，较单一使用软对抗线导鱼雷的成功概率提高了20％～36％。

We propose a torpedo defense tactic for a vessel cooperative defense against wire-guided torpedo with a rocket assisted noise-jammer and a hovering depth charge, named hard-kiU and soft-kill anti-torpedo weapons. We simulate the board angle of guided submarine based on the firing principle of a wire-guided torpedo, establish a model of cooperative defense against a submarine-launched wire-guided torpedo using a rocket-assisted noise-jammer and a hovering depth charge, determine the deploying strategy of hard-kill and soft-kill anti-torpedo weapons and evading course of surface ship through the optimization method in operational research, and compare the success probabilities of the cooperative defense with hard-kill and soft-kill anti-torpedo weapons and the defense with single rocket-assisted noise-jammer via simulations. The results show that the proposed tactic can increase success probability by 20%-36% compared with only using a rocket assisted noise-jammer.
