Maneuver Strategy of Terminal Guidance of Near Space Vehicle via Differential Game Theory

Abstract

AbstractFor the terminal guidance stage of the near space vehicle offensive and defensive countermeasures, the maneuver penetration strategy of the vehicle is studied based on the differential game theory. First, linearize the relative motion relationship between the vehicle and the interceptor. Second, the zero-control miss distance is defined, and the quadratic objective function is designed and solved. Final, the maneuver strategy of the differential game is simulated and verified. The results show that compared with the square wave maneuver, it not only reduces its own energy consumption by 67.6%, but also increases the energy consumption of the interceptor by 93.3% and increases the missed distance by 10.86 m. The differential game maneuver strategy will significantly increase the maneuver penetration capability of the vehicle.KeywordsNear spaceDifferential gameTerminal guidanceManeuver strategy
