Electromagnetic coil launch is an important branch of electromagnetic launch (EML) technology, which is suitable for launching anti-torpedo torpedo (ATT). This paper focuses on the EML parameters and the interception probability of the EML two ATTs salvo. Based on the launching model of a multi-stage coil launcher, the trajectory model of the ATT and the attacking torpedo, a calculation method for the EML two ATTs salvo parameters is proposed, with the conditions of capture and interception given reasonably. An adaptive particle swarm optimization (APSO) algorithm is proposed to calculate the optimal launching parameters, by designing the adaptive inertia weight and time-varying study factors. According to the analysis of the simulation with Monte Carlo method, EML will improve the interception probability effectively, and the interception probability is affected by the launching range. The results demonstrate good performance of the proposed APSO in calculating EML parameters for the two ATTs salvo in certain combat situation. Implications of these results are particular regarding the command and decision in the anti-torpedo combat.

电磁线圈发射是电磁发射（EML）技术的一个重要分支，适用于发射反鱼雷鱼雷（ATT）。本文重点研究 EML 两个 ATT 齐射的 EML 参数和拦截概率。基于多级线圈发射器的发射模型、ATT和攻击鱼雷的弹道模型，在合理给出捕获和拦截条件的情况下，提出了EML两个ATT齐射参数的计算方法。通过设计自适应惯性权重和时变研究因子，提出了一种自适应粒子群优化（APSO）算法来计算最优发射参数。根据 Monte Carlo 方法的仿真分析，EML 将有效提高拦截概率，拦截概率受发射范围的影响。结果表明，在某些战斗情况下，所提出的 APSO 在计算两个 ATT 齐射的 EML 参数方面具有良好的性能。这些结果对反鱼雷作战中的指挥和决策具有特殊意义。
