摘　　要：针对传统的波束倾角固定引信无法满足新一代防空导弹引战配合需求的问题,提出了基于二维波束控制引信的起爆控制方法。该方法通过将平面相控阵技术引入引信天线,实现了波束的二维控制。在此基础之上建立了引信最佳起爆角和起爆方位模型并设计了基于波束分档前提下的起爆控制算法,保证了二维波控引信与定向战斗部的有效配合。在H平面内,根据起爆方位角来选择战斗部的起爆点;在E平面内利用波束倾角分档控制和延时调整炸点的方法,把修正后所对应的起爆角与动态破片飞散角差值作为起爆控制量,实现智能化引战配合。仿真分析表明该方法可实现战斗部适时起爆并将破片飞散方向对准目标,显著提高了引战配合效率。The traditional fuze beam angle is fixed, which caiYt meet the demand of air defense missile. Aiming at this problem, a new method of initiating control based on two-dimension beam controlled fuze was proposed in this paper. This method introduced the fuze antenna based on planar phased array technology and two-dimension beam control was realized. On this basis, a new model of the optimum detonating angle and initiating direction was established and the initiating control algorithm based on beam step was designed, which guaranteed the ef-fective cooperation of two-dimension beam controlled fuze and aimed warhead. In the H-plane, an appropriate initiation point of the aimed warhead according to the discrete azimuth can be chosen. In the E-plane,according to the discrete beam angle and adaptive detonating delay algorithm, it can realize intelligent coordination that taking the difference between the detonating angle which has been corrected and dispersion directional angle of center fragment as controlled variable of fuze action Simulation indicates that this method can control adaptively the detonation of warhead and make the fragment aim at the target. The coordinated efficiency of fuze and war-head can be improved very well.
