为满足定向战斗部对多光束周视激光引信的延时和方位要求，针对引战配合问题，依据激光探测原理建立了弹目交会过程中最佳起爆延时和最佳起爆方位角的数学模型。仿真结果表明：所建立的最佳起爆延时与方位角模型正确，且与弹目视线角、目标初始方位角、弹目间距、弹目相对速度、破片飞散速度、目标和弹体外型参数等信息有关。根据多光束周视激光引信系统提供的信息参数，可计算出最佳起爆延时与最佳起爆方位角，能够控制战斗部适时定向起爆，实现对目标的有效打击。

In order to meet the delay and azimuth requirements for the multi-beam circum-directional laser fuze, a mathematical model of the optimum detonating delay and the optimum detonating azimuth angle during the process of bombing is established according to the laser detection principle. The simulation is carried out by using Matlab. The results show that the model is related to the information such as the target line of sight, the distance between the projectile, the relative velocity of the missile, the flying speed of the fragment, the shape parameters of the target and the missile. Using the information provided by the multi-beam circum-directional laser fuze system, the optimum detonating delay and the optimum detonating azimuth angle can be determined, and the warhead can be controlled in a timely direction to achieve effective attack on the target.
