针对高超声速滑翔式飞行器突防导弹防御系统的问题,设计了一种基于威胁时间窗的摆动式机动突防方法,联合地基雷达、拦截导弹和HGV建立了毁伤概率模型。通过摆动式机动方法控制HGV暴露的RCS。运用极大极小值原理设计了最优突防弹道,使飞行器在所有威胁时间窗内毁伤概率的极大值取极小并进行了数字仿真。仿真结果表明,该方法在牺牲一定航程和航时的条件下能有效降低HGV突防过程中被毁伤的概率,增强其生存能力。 Aiming at the problem of HUD missile defense system in hypersonic gliding aircraft, a swinging method based on threat time window is designed. The damage probability model is established based on ground-based radar, interceptor missile and HGV. Control of HGV-exposed RCS by oscillatory maneuvering. By using the principle of maxima and minima, the optimal shot-and-ballistic trajectory is designed, which minimizes the maximum damage probability of the aircraft and performs digital simulation in all threat time windows. Simulation results show that this method can effectively reduce the probability of damage during HGV knockout and enhance its viability under the condition of sacrificing a certain range and flight time.
