Description

Second-order damping aircraft attack and defense game method, equipment, medium and product aiming at unknown strategy counterpart Technical Field The application relates to the technical field of aircrafts, in particular to a second-order damping aircraft attack and defense game method, equipment, medium and product aiming at an unknown strategy counterpart. Background In recent years, with the development of unmanned technology, manufacturing technology, information technology and artificial intelligence technology, and the remarkable improvement of the level of on-board hardware, unmanned aerial vehicle cluster countermeasure technology has received high attention and has been greatly developed. Advances in aircraft cluster gaming technology have prompted multi-aircraft interception technology to be an important research topic. The interception problem of attacking a plurality of defense areas by a plurality of aircrafts is the most common operational scene in cluster countermeasures, and the opponent aircrafts have more efficient reconnaissance striking capability due to the dispersibility, intelligence and flexibility of the opponent aircrafts, so that the traditional defense system is difficult to perceive and reconnaissance the opponent target, and even if the reconnaissance target is in countermeasures, the burden of an air defense system is increased due to a plurality of targets, and finally the defense system is disabled. Therefore, the method adopts the battle thought of 'anti-group' outside the original air defense system, and the secret air perception reconnaissance and the refusal of the defending net have important application value. At present, many works are focused on a simple dynamics model of a first-order integrator, but in an actual air combat scene, the speed of an aircraft is continuous, the thrust has size and direction constraints, and the first-order integrator model is difficult to simplify. In view of the current state of research on aircraft gaming countermeasure, the design of an attack and defense game strategy for a second-order damped aircraft is a quite challenging problem. The related researchers combine a geometric analysis method and a differential game theory, a set of chase game strategies is provided for a second-order damping dynamics model, and the optimality of the strategies is proved through a Hamilton-jacobi-Issacs (Hamilton-Jacobian-Essaxophone) equation, but the method is difficult to solve under the complex dynamics constraint. Other researchers take a second-order Dubin vehicle dynamics model as a research object, and under the constraint condition that the Dubin vehicle has the minimum turning radius, the win-win strategy and the full condition of the defender are provided. However, unmanned aerial vehicles and other aircrafts in real environments have speed damping items and thrust constraints, and therefore, related technical schemes lack consideration of the speed damping items and the thrust constraints, so that a second-order damping aircraft attack and defense game method aiming at unknown strategy opponents is needed, and the intelligent attack and defense game problem of many-to-many second-order damping aircrafts is solved. Disclosure of Invention The application aims to provide a second-order damping aircraft attack and defense game method, equipment, medium and product aiming at an unknown strategy counterpart, which can solve the problem of intelligent attack and defense game of a many-to-many second-order damping aircraft.
