摘　　要：海战场环境中,箔条幕自卫干扰构设前由于未充分考虑风向、风速等因素,容易导致干扰失败,且无定量化的布放模型。针对此问题,提出一种新的箔条幕干扰构设方法。基于箔条幕干扰机理分析,构建干扰场景模型,具体包含导弹运动模型、舰船运动模型和箔条幕形态模型;综合考虑干扰有效性和资源损耗性,提出采用灰狼算法进行箔条幕干扰构设方案求取的思路,建立相应约束条件(遮蔽有效性约束条件、质心拖引有效性约束条件和干扰能力约束条件)、目标函数和补弹策略,且采用Logistic混沌映射和反向学习策略改进灰狼算法。最终通过仿真案例分析得出以下结论:所提出的箔条幕干扰构设方法寻优速率快,可保证整个对抗过程中舰艇始终能够进行有效自卫干扰。初始时刻构设的箔条幕轴线基本与弹目轴垂直,而箔条幕质心基本处于弹目轴线附近。风向与风速对自卫干扰效果影响较小,初始弹目距离主要影响箔条弹用量,初始反舰导弹攻击方向对自卫干扰效果影响较为明显。当从舰艇尾向进行攻击时,干扰效果最好;相反,从舰艇艏向进行攻击时,干扰效果最差。The chaff screen jamming construction in the sea battlefield environment is easy to lead to self-defense jamming failure due to the insufficient consideration of wind direction,wind speed,and other factors and the lack of relevant quantitative models.To address this problem,a new chaff screen jamming construction method is proposed.On the basis of the analysis of the chaff screen jamming mechanism,the jamming scene model is constructed,including the missile movement model,the ship movement model,and the chaff screen morphological model.With comprehensive consideration of the effectiveness of jamming and the depletion of resources,the idea of using the gray wolf algorithm to obtain the chaff screen jamming construction scheme is proposed.The corresponding constraints(shielding effectiveness constraint,centroid drag validity constraint,and jamming ability constraint),objective function and replenishment strategy are constructed,and the gray wolf algorithm is improved by logistic chaotic mapping and reverse learning strategy.The following conclusions are drawn through the simulation case analysis.The proposed chaff screen jamming construction method has a fast optimization rate and can ensure that ships can always carry out effective self-defense jamming during the entire confrontation process.The chaff screen axis constructed at the initial moment is basically perpendicular to the bullet axis and the chaff screen center of mass is basically near the bullet axis.The wind direction and wind speed have less influence on the self-defense jamming effect.The initial bullet distance mainly affects the amount of chaff and the initial anti-ship missile attack direction has a more obvious impact on the self-defense jamming effect,which is the best when attacking from the rear of the ship and the worst when attacking from the bow.
