潜艇组合使用声抗器材防御来袭鱼雷是目前潜艇鱼雷防御领域的研究热点。在深入研究诱饵组合使用模型基础上,采用相对移动线方法,给出了组合使用声诱饵时小口径声诱饵初始航向计算方法;提出基于遗传算法的潜艇组合使用声诱饵防御鱼雷技术,解决了由于决策参数增多,传统穷举统计方法计算量急剧增加问题,实现了潜艇组合使用大小口径声诱饵防御来袭鱼雷能力。仿真结果表明:该技术可使潜艇防御鱼雷成功概率提高14%以上。

The combination of using acoustic countermeasures equipment is the hotspot in the field of torpedo defense of submarine. Based on the study of the combined use of decoy and the relative moving line method, the method of calculating the small caliber decoy’s initial course is given; Then, based on genetic algorithm, the technology of submarine torpedo defense by combination of decoys is proposed, which solves the problem that the amount of calculation of traditional exhaustive statistics method increases dramatically when the decision parameters increase, and realizes the ability that submarine can combine use the small and big caliber decoy to defend the incoming torpedo. The simulation results show that the technology can improve the submarine’s survival probability by more than 14%.
