【摘要】 针对动能拦截器的拦截,研究了弹道导弹在大气层外作无动力飞行时的突防机动问题。分别建立了突防导弹和动能拦截器的六自由度运动学和动力学模型以及它们之间的相对运动学模型,突防弹采用了最优突防策略,拦截器采用了最优末制导,仿真得到了突防弹在正弦机动下的脱靶量,并研究分析了突防机动周期、突防机动时机等因素对突防效果的影响。更多还原

【Abstract】 The problem of the penetration by ballistic missile’s maneuver is studied in this paper when the missile flies without power in the exoatmosphere and be intercepted by Kinetic Kill Vehicle. The six degree-of-freedom motion model and dynamics model of the penetration missile and the KKV are constructed. And the complex model containing ballistic missile and interceptor is also constructed. The optimization scheme of the penetration of ballistic and optimization guidance law of the KKV are used. The feasibility and validity of the penetration tactic of ballistic missile are validated through simulation.更多还原
