摘　　要：针对传统的目标毁伤计算时未详细考虑激光近炸引信的起爆延时,从而导致对目标毁伤效能的计算与实际存在一定差距的问题,提出激光近炸引信弹目交会条件下基于最佳起爆延时的目标毁伤建模方法。推导了使引信处于最佳近炸位置的弹目交会近炸最佳起爆延时函数;在确定最佳起爆延时的基础上,结合对破片群飞散特性的分析,建立了激光近炸引信对目标的毁伤概率计算模型。仿真分析了不同因素对近炸引信最佳起爆延时的影响。通过模拟近炸引信对目标的毁伤实验结果可以看出激光近炸引信的起爆延时影响着最终的目标毁伤概率,这将为提高激光近炸引信的毁伤效能提供参考。In response to the problem of traditional target damage calculation not fully considering the initiation delay of laser proximity fuze,which leads to a certain gap between the calculation result of target damage efficiency and the actual situation,this paper proposed a target damage modeling method based on the optimal detonation delay of the laser proximity fuze under missile-target intersection.First,the optimal initiation delay time function for the proximity detonation under missile-target intersection was derived to keep the fuze in the optimal proximity position.On the basis of determining the optimal initiation delay and analyzing the dispersion characteristics of warhead fragments,a calculation model for the damage probability of laser proximity fuze to the target was established.Finally,under the given parameter conditions,the effects of factors such as warhead fragment dispersion angle,missile-target distance,and missile-target relative velocity on the optimal detonation delay time of the proximity fuze during missile-target intersection were simulated and analyzed.The simulation results showed that the initiation delay of laser proximity fuze affected the final target damage probability.
