根据常规弹药最佳定向起爆要求,针对弹目交会环境,建立脉冲激光周向探测系统单次和二次扫描最佳起爆延时模型和最佳起爆方位角模型.运用Matlab对模型参量进行数值仿真,分析探测方位角、弹目间距和目标俯仰角对最佳起爆延时和起爆方位角的影响.结果表明:当激光扫描到单次目标时,最佳起爆延时随弹目之间距离的增大而增大,随探测方位角的增大先减小后增大,最佳起爆延时的变化范围在0~20ms之间;当脉冲激光周向探测系统扫描到二次目标时,在大部分时间内最佳起爆延时时间为0ms;在非零区域内,最佳起爆延时随弹目之间距离的增大而增大,随探测方位角的增大先变大后变小.
According to the detonation requirements of conventional ammunition, the optimal initiation time delay model and the optimal initiation azimuth model of single and double scan of the pulse laser circumferential detection system are established for the projectile rendezvous environment.The numerical simulation of the model parameters is carried out by using Matlab , The effects of azimuth, projectile pitch and target pitch angle on the optimal initiation delay and initiation azimuth were analyzed.The results show that when laser scanning reaches a single target, the optimal initiation delay varies with the distance between the projectile Increases with the increase of azimuth angle, then decreases and then increases with the increase of azimuth angle of detection. The optimum detonation delay varies from 0 to 20 ms. When the pulse laser scanning system reaches the second target, The optimum initiation delay time is 0 ms for most of the time. In the non-zero region, the optimum initiation delay increases with the distance between the projectiles and increases and then decreases with the increase of azimuth .
