Lethality Analytical Model of Hit-to-Kill Kinetic Kill Vehicle Against Submunition Payloads

针对直接碰撞杀伤动能拦截器对子母弹道导弹弹头毁伤问题,对动能拦截器和子母弹头目标特性进行了分析,基于体积重叠分析提出了子弹毁伤判定方法,建立动能拦截器末端遭遇弹道模型,并通过引入射击线技术对毁伤子弹数进行了估算,建立了动能拦截器对子母弹头毁伤快速分析模型.算例与分析表明,利用该模型可有效分析碰撞角、碰撞点等因素对子母弹头毁伤概率的影响,研究结果可为动能中段反导毁伤效能评估和拦截模式选择提供参考.

An analytical model was presented for predicting rapidly the lethality of hit-to-kill kinetic energy kill vehicle against ballistic missile carrying submunition payloads. The geometry of submunition payloads and kill vehicle were described and the lethality determination approach was proposed based on overlapping volume analysis. In addition the endgame kinematics was modeled and the killed fraction of submunition was approximated with the shot line technology. The endgame simulation shows that the influences of strike angle and impact point on the killed fraction of submunition can be obtained with the application of the lethality analytical model. It will be a useful tool for lethality assessment and interception mode adoption about hit-to-kill kinetic kill vehicle against submunition payload in midcourse phase.
