A multi-missile cooperative trajectory planning method for defense penetration

Abstract

The invention provides a multiple missile collaborative ballistic planning method to deal with penetration. The method comprises the specific steps that step 1, based on the radar equation, a radar threat quantification model is established to describe the threat of a radar detection area to a missile; step 2, a collaborative control model is established, the collaborative control model comprisesa collaborative time control model and a collaborative angle control model; step 3, a collaborative attack problem is converted into a nonlinear optimal control problem which is solved based on a hp-self adaptive Radau pseudospectral method, which means at one moment of the flight, the remaining flight time of each missile is determined, whether or not a collaboration is necessary, if necessary, the time for the collaborative attack is calculated and the missile to be adjusted is determined, and the collaborative ballistic planning is conducted on the missile needs to be adjusted. According tothe multiple missile collaborative ballistic planning method, multiple missiles attacking a target on the same attacking time and with the same attacking angle is ensured; meanwhile, the radar detection threat is smallest during the flight, and the comprehensive combat effectiveness is effectively improved.

Description

technical field [0001] The invention relates to a coordinated ballistic planning method that realizes attack time and attack angle coordination when controlling multi-missile cooperative operations, and satisfies the minimum radar threat, and belongs to the technical field of aviation and aerospace ballistics and guidance. Background technique [0002] Future warfare will be an offensive and defensive confrontation between combat systems, especially the confrontation between the attack system based on precision-guided weapons and the increasingly strengthened modern defense system. In a complex battlefield environment, radar, as a main detection method of the enemy, poses a strong threat to the penetration of missiles. [0003] In order to achieve effective penetration and improve comprehensive combat effectiveness, the U.S. military took the lead in proposing the concept of coordinated operations and achieved a series of research results. [0004] At present, multi-missile...

Problems solved by technology

Although some existing research methods can achieve multi-missile coordinated attack targets, the research objects are mainly for low-speed aircraft, and most of these methods linearize the equation of motion under the assumption of a small angle, which has a large error for high-speed maneuvering missiles
