高超声速滑翔式飞行器摆动突防设计

Design of Weaving Penetration for Hypersonic Glide Vehicle

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。

As to the strategy of penetration against the Missile-Defence-System for Hypersonic Glide Vehicle （HGV）, an approach of lateral weaving maneuver based on threat time-window was proposed. A damage probability model was established based on the combination of radar, missile and HGV. The exposed Radar Cross Section （RCS） of HGV was controlled by lateral weaving maneuver. The optimal penetration trajectory was designed based on the minimax theory, which minimized the maximal damage probability of HGV for all the threat time-windows. Simulation was made, and the result demonstrated that this approach can reduce HGV＇s probability of being damaged, and improve it＇s survivability during penetration effectively at the cost of more voyage and time.
