摘　　要：空基反导以其部署灵活、响应速度快等特点而受到各军事大国高度重视。针对常见的规划弹道,对处于飞行中段的弹道导弹进行拦截具有诸多优势,因此,为拦截器设计一种精确、能耗最优的中制导律至关重要。首先,本文基于简化的弹-目相对运动学模型,运用LQR理论设计了一种新的能量最优空基反弹道导弹中制导律;其次,根据给定的弹-目初始条件,通过数字仿真对所设计的制导律进行了验证。结果表明,本文提出的制导律可以较好地满足空基拦截弹道导弹中制导要求。The air-based anti-missile method has been drawn high value by many great military powers in the world for its flexible deployment and quick reaction. It is extremely important to design a precise and energy optimal midcourse guidance law for the interceptor considering the advantages to intercept the ballistic missiles in the midcourse according to some common planned trajectory. Firstly,this thesis designs a new midcourse guidance law for air-based intercepting ballistic missile based on LQR theory by using a simplified relative kinematic model of ＂Interceptor-Target＂,then the new guidance law is verified by digital simulation with the initial condition of the ＂Interceptor-Target＂. The results show that the new designed midcourse guidance law could meet the requirement of the midcourse guidance properly in an airbased anti-missile system.
