航天器末端拦截自适应博弈策略

针对航天器末端拦截博弈问题，基于微分对策理论研究了各星的博弈策略。根据拦截空间是否具有防御器将博弈态势分为双星博弈和三星博弈。首先考虑拦截器与目标的双星博弈态势，以终端脱靶量为指标设计了相对博弈策略，并提出时间分析方程以提高策略对不同拦截态势的自适应性。然后，考虑具有防御器的三星博弈态势，提出了博弈切换策略将其化为分段双星博弈，并将双边时间方程扩展到三星博弈中，使拦截器在不被防御器反拦截的情况下，实现对目标的快速拦截。最后仿真分析了博弈策略与时间分析方程对航天器拦截博弈问题的有效性。

Adaptive Game Strategy of Spacecraft Terminal Interception

Aiming at the terminal interception game problem of the spacecraft, the strategies of satellites are studied on the basis of the differential game theory. According to whether there is a defender in the intercept space, the game is divided into the two-satellite game or the three-satellite game. Firstly, consider the two-satellite game situation with an interceptor and a target. Then, the relative game strategies are designed with treating the terminal miss as a cost function. And the time analysis equation is proposed to improve the adaptivity of strategies for different intercept situations. Furthermore, consider the three-satellite game with a defender. The game switching strategy is proposed to decouple the game into the segmented two-satellite games. And the bilateral time equation is extended in the three-satellite game, which causes the interceptor to intercept the target rapidly, and not to be intercepted by the defender. Finally, the simulations analyze the effectiveness of the game strategy and the time analysis equation to the intercept game problem of the spacecraft.
