Multi-aircraft anti-interception collaborative strike guidance method and device and aircraft

Abstract

The invention provides a multi-aircraft anti-interception collaborative strike guidance method and device and an aircraft. According to the method, the state data of an attack aircraft, the state data of an interception aircraft and the state data of a target object are obtained, wherein the state data comprise position information, speed and acceleration; and the guidance law of the attack aircraft is obtained according to the state data and a three-body differential game model, wherein the three-body differential game model is established by reducing the order of a combat linear kinematics and dynamics model according to a zero-control miss distance and according to the reduced-order combat linear kinematics and dynamics model and a time multiplier, the time multiplier is introduced to unify the terminal time of all the reduced-order models, global performance indexes are established, the saddle point solution is obtained based on the differential game theory, and the guidance law is optimal for the three parties. According to the invention, combat that the multiple aircrafts penetrate through the interception of the missile group is realized, so that the multiple aircrafts can avoid the interception of the interception aircrafts with the maximum maneuverability and accurately hit a target object.

Description

technical field [0001] The present disclosure relates to the field of aerospace technology, and in particular to a multi-aircraft anti-interception coordinated strike guidance method, device and aircraft. Background technique [0002] Guidance is the technology and method of guiding and controlling the aircraft to fly to the target object or predetermined orbit according to certain rules. [0003] The traditional guidance methods are all aimed at the two-body strike problem of the attacking aircraft striking the target object. From the perspective of optimality, the guidance law of the optimal control can give the optimal solution under the condition that the terminal condition is satisfied under the given linear model , when the model is nonlinear, some nonlinear control or guidance laws of ballistic planning can complete the guidance. [0004] When the attacking aircraft hits the target object, there will be intercepting aircraft based on various anti-missile systems to i...

AI Technical Summary

Problems solved by technology

The guidance law obtained by the above-mentioned two-party modeling method only for the attacking aircraft and the target object cannot meet the situation of three-party combat, so the accuracy of the obtained guidance law is not high
