Abstract: According to aimed warheads 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 initia
