DQN and differential game-based orbit pursuit game strategy method

The invention discloses an orbit pursuit game strategy method based on DQN and differential game, and belongs to the technical field of aerospace. The method comprises the following steps: designing a pursuit spacecraft and escape spacecraft control law pattern library according to a differential game theory, and constructing a game confrontation action set; the purchaser selects the game confrontation action set through a DQN model, and the escaper randomly selects the game confrontation action set; performing orbit deduction on the acquired pursuer and escaper through a spacecraft orbit dynamics model; and adjusting the DQN model according to the orbit deduction result until the training loss of the DQN model is converged to be stable, and generating an orbit pursuit game strategy. According to the method, the operation range of the pursuit is enlarged, and meanwhile the pursuit can rapidly and accurately intercept the pursuit. 本发明公开了一种基于DQN与微分博弈的轨道追逃博弈策略方法，属于航空航天技术领域。方法包括根据微分博弈理论，设计追击航天器与逃逸航天器控制律样式库，构建博弈对抗
