Guidance rocket vertical attack guidance method based on falling point estimation

Abstract

The invention discloses a guidance rocket vertical attack guidance method based on falling point estimation. By using the method, a terminal guidance stage can be entered at a large falling angle, andthe requirement of the missile terminal guidance stage on overload capacity is lowered. In the early stage of the falling arc section, a trajectory is adjusted in a manner of firstly pulling up and then pressing down, so that a guidance rocket can enter the terminal guidance stage at a nearly vertical angle, the guidance control difficulty of the terminal guidance is reduced, vertical strike canbe effectively realized, and the attack efficiency of a warhead is improved. In addition, by introducing a cross point miss distance, the optimal control opportunity of the pull-up operation and the press-down operation in the third stage can be effectively obtained, and the mode is simple and reliable. Meanwhile, the ideal trajectory is tracked in the first stage, the trajectory is adjusted in the second stage according to the zero-effect prediction miss distance, the maneuverability of a rocket projectile on the whole trajectory is fully utilized, and the method has the advantages of being simple in algorithm, easy to realize, wide in attack range and the like.

Description

technical field [0001] The invention relates to the technical field of ammunition guidance control, in particular to a vertical attack guidance method for guided rockets based on impact point estimation, which can be used for guided rockets, guided shells, guided missiles, guided missiles and other guided weapons and equipment. Background technique [0002] For most types of warheads, the falling angle is an important factor affecting the power of the warhead. Taking the anti-personnel blasting warhead as an example, since the fragments of the warhead are scattered mainly near the normal plane of the projectile axis, the falling angle When the warhead fragments are small, most of the warhead fragments fly to the ground and sky at close range, and the power of the warhead is greatly affected. Taking the penetrating warhead as an example again, a large drop angle is conducive to the penetrating effect of the warhead. In the case of a small drop angle, the penetrating warhead i...
