同步扫描周视脉冲激光引信多探测点最佳起爆建模及仿真

Modeling and simulation of multi-detection point optimal initiation of synchronous scanning panoramic pulse laser fuze

周视激光引信通常仅根据单次测量的目标方位和距离解算最佳起爆时间和起爆方位角,精度不高,另一方面,引信无法判别目标真伪,易发生"虚警"或误炸。基于同步扫描周视脉冲激光引信工作原理,分析了弹目交会过程中多个探测点的方位、距离及其位置坐标,建立了基于多探测点的目标速度模型,对目标速度进行计算以辨别目标真伪。解算了目标特征几何中心位置,建立了最佳起爆时间和方位角计算模型,使战斗部获得最大毁伤效能,并分析了最佳起爆时间和方位角的影响因素。研究可为周视激光引信目标真伪辨别和定向起爆控制提供参考。

Panoramic laser fuze usually calculates the optimal initiation time and initiation azimuth only based on single measured target direction and distance, the calculation accuracy is low. On the other hand, fuze can not distinguish the authenticity of targets, it is easy to cause "false alarm" or accidental bombing. Based on the working principle of the synchronous scanning panoramic pulse laser fuze, the direction, distances and position coordinates of multiple detection points were analyzed. The target velocity model based on multiple detection points were established, which can calculate the target speed and judge whether the target was true. The geometric center position of the target feature was solved, and the optimal initiation time and azimuth calculation model were established to obtain the maximum damage effectiveness of the warhead. The influence factors of the optimal initiation time and azimuth were analyzed. The research can provide a reference for the target identification and directional initiation of the panoramic laser fuze.
