A Method of Surrounding Escapable Space Target by Combining Game with Optimization

The orbital pursuit-evasion game issue, as an important task form of space offensive and defensive confrontation, has great research significance. Aiming at the problem of multi-satellites rounding up an escapable target, a method combining game with optimization is proposed. The pursuing satellites and escapable target are regarded as two game sides in several decision-making cycles. Considers the expected purpose, fuel consumption and safety of both sides comprehensively to design their payoff functions. In order to reducing the value of their respective payoff functions, the maneuvering strategies of both sides are optimized based on the particle swarm optimization algorithm. The simulation result shows that this method can track and surround target for a long time, and support the space orbit game mission effectively.
