Description
Technical Field
The invention relates to the technical field of air defense weapons, in particular to a fixed-distance combat-guiding matching method for intercepting and damaging a hypersonic target along a track.
Background
The seeking guidance is that the projectile seeks, tracks and destroys a target. When a seeker on the projectile receives infrared, radio, light or sound signals radiated or reflected from the target, a guidance system on the projectile directs the projectile along the signal toward the target. At present, when the targeted guided air-defense missile is adopted at home and abroad, when the ultra-high sound velocity target is dealt with, the hypersonic velocity target cannot be destroyed by the guiding cooperation method of the side-looking fuse of the conventional anti-conventional missile target because the reentry speed of the hypersonic velocity gliding body is high, the RCS is small and the flying overload of the reentry warhead is large. The most representative is the patrioter series missile in the United states, and the patrioter' PAC-1 missile fuze is the traditional side-beam fixed-angle radio-pulse Doppler proximity system and mainly deals with the conventional target. The main measure for improving the 'patriot' PAC-2 missile fuze is to add a group of 25-degree-inclination antennas on the basis of the original group of antennas with large lateral inclination angles so as to deal with the target of a tactical ballistic missile. However, actual combat shows that when the speed of the bullet eyes exceeds Mach 10 in a meeting, the PAC-2 warfare system is not well matched, only can hit the tail of a target, and cannot kill the bullet. Therefore, the forward GIF fuze with an active millimeter wave guide head and a fuze integrally designed is adopted in the 'patrician' PAC-3 missile, the design mainly aims to solve the problem of detecting the tail end of a reverse-rail intercepted high-speed target, but aiming at a hypersonic target (the speed is greater than Mach 5), the method inevitably causes higher interception speed of the interceptor, so that the temperature rise of a guide head protective cover of the interceptor is higher due to shock waves, and particularly the thermal saturation effect of an infrared guide head is caused.
Therefore, in order to better intercept an incoming hypersonic target, an interceptor is launched on a predicted track of an incoming weapon in advance, and an optimal distance starting engagement coordination method is needed to be provided, so that the purpose of efficiently damaging the hypersonic target is achieved.
