Radar scene matching terminal guided missile flight trajectory planning method

Abstract

The embodiment of the invention provides a radar scene matching terminal guided missile flight trajectory planning method, and relates to the technical field of missile trajectory planning methods. According to the method, the planning operation time can be greatly shortened, the application range of a launching area is increased, one set of digital reference map can be shared when multiple adjacent targets are hit, and the radar reference map guarantee capability and the weapon combat effectiveness can be effectively improved. The method comprises the steps of 1, preprocessing a radar reference map, and adjusting the resolution of the radar reference map to complete binarization processing; 2, planning a tail-section flight path, planning a tail-section attack direction, generating an envelope control point, and generating a tail-section flight path; step 3, performing control guidance planning, designing a control guidance rate, and realizing flight trajectory shift planning; 4, planning the change of the strike point, and planning the navigation correction amount of the changed strike point; and 5, planning available emission areas, and checking and generating an available emission area list.

Description

technical field [0001] The invention belongs to the technical field of missile trajectory planning methods, in particular to a radar scene matching terminal guidance missile flight trajectory planning method. Background technique [0002] Radar scene matching The terminal guided missile is an important precision-guided weapon. It mainly uses the synthetic aperture radar seeker device installed on the head of the missile to detect the radar scene around the target in real time. Matching and identification are carried out to obtain the relative positional relationship between the missile and the surface reference object, so as to determine the relative position of the missile and the target point, obtain precise guidance information, control the missile to fly to the target along the final flight track, and achieve precise hit on the target. [0003] The radar scene matching terminal guidance missile flight trajectory planning is mainly based on the launch area and strike targ...

AI Technical Summary

Problems solved by technology

[0004] In the prior art, the flight trajectory planning of the radar scene matching terminal guided missile is mainly based on the clear launch point and target point, and the active segment is used to adjust the adaptation deviation. The method completes the planning and design of the full trajectory of the missile flight, and realizes the evaluation of the strike accuracy of the terminal guidance of the target through a large number of trajectory simulations. There are problems such as the small adjustable range of the launch point, the unchangeable target point, and the time-consuming planning operation.
