根据定向起爆部对引信提出的时间匹配和空间匹配的要求，针对弹目交会相对运动环境，在惯性坐标系下3个相互垂直的2维平面内，建立了弹目相对速度下脉冲激光方位探测引信系统的最佳起爆延时和最佳起爆方位角模型，并对相关时间匹配和空间匹配特性进行了量化及数值仿真分析。结果表明: 模型与弹目交会角、目标初始方位角、发射激光束与弹丸速度夹角、引信中心至目标尾部距离、目标外型参数、目标速度、破片飞散速度、弹丸内部结构参数、弹丸速度等目标区环境信息有关。

According to aimed warhead’s request of space matching and time matching for fuze, and the relative motion environment of missile target encounter, this paper establishes a optimum detonating delay time model and a optimum detonating azimuth model of pulsed laser position detection fuze system in three mutually perpendicular two-dimensional planes of inertial coordinate system. Quantified and numerical simulation of corresponding space matching and time matching is also performed. The study of time and space matching characteristics for pulsed laser azimuth detection fuze, lays a theoretical foundation for parameter design of appropriate security and detonation control system.The results show that the model has the relationship with projectile target crossing angle, the initial target azimuth, the angle between the laser beam and projectile, the distance from fuse to the target, the target shape parameters, the target speed, the fragment velocity, the projectile internal structural parameters, the projectile velocity and other environmental information.
