Highlights Optimal Strategies for the evader are designed under various conditions. The effects of orbit energy and orbital radius on escape strategy are illustrated. Pursuer’s optimal delta-V’s asymmetrical distribution law is unveiled. A correction method is designed to reduce pursuer’s delta-V. Effects of incomplete information on strategies are discussed.
Abstract This research investigates the orbital pursuit-evasion games with impulsive maneuvers in long-distance interception scenarios. Specifically, this paper examines the influences of escape impulses, with different directions, applied by the evader on the intercept-correction delta-v () of the pursuer that is already on an interception orbit. After obtaining the evader’s strategies based on maximizing the under different circumstances, it is found that, with the knowledge of the evader’s best strategy, the pursuer could make smaller by adjusting its initial interception orbit. Then, a method to modify the initial orbit with energy constraints is designed so that the pursuer can match the evader’s escape maneuver with less delta-v to prepare. Finally, this paper summarizes the best strategies of both sides after considering the initial trajectory adjustment and discusses the impact of incomplete information on tactics in orbital pursuit-evasion games.
