配合引信定向探测起爆控制参数选择问题，提出了一种定向战斗部激光引信12分元探测定向起爆控制建模方法。该方法基于建立的12分元激光探测模型，通过对目标方位的判别，实施对定向战斗部的起爆方位控制。结合目标易损性模型，通过仿真不同弹道及起爆时机对目标造成毁伤的效果，得到了定向战斗部激光引信延时时间与毁伤效果匹配关系。仿真结果表明，对于空中高速小目标，引信延时时间、脱靶量及破片飞散角等参数的匹配对毁伤效果非常重要，当延时时间不大于2 ms时，脱靶量小于8 m时平均毁伤概率达到0.6以上，脱靶量大于10 m时平均毁伤概率小于0.5。建立的模型可综合分析延迟时间、脱靶量等参数对定向战斗部毁伤效果的规律。

Aiming at optimal detonation controlling of directional warhead fuze, detonation control simulation for dodecagon-detection laser fuze was presented. Based on dodecagon-detection model, the detonation orientation was controlled by discriminating target orientation. Combining with target vulnerability model, effect of delay time on damage was simulated and analyzed on different trajectories. The simulation results show that it is very important to match the parameters such as fuze delay time, miss distance and fragment fly scattering angle for high-speed small targets in air. When delay time is no more than 2 ms, the average damage probability, if miss distance is within 8 m, is more than 0.6, and is less than 0.5 if miss distance is over 10 m. The model can comprehensively analyze the damage effects with different delay time and miss distances.
