摘　　要：在地基助推级反导作战过程中,由于目标弹道导弹的加速度很大,造成拦截弹失去了加速度优势。文中针对单级短程固体弹道导弹的助推级中段拦截,推导出一种能量最省的制导律,不需要拦截弹的加速度大于目标加速度。二维闭环仿真结果显示,在满足制导精度的基础上,拦截弹的切向和法向过载均较小,能够满足作战需求。In the ground-based missile defense operational process,due to the large target acceleration,it often makes intercept missile loss acceleration advantage.This paper considers the condition that a single-stage short-range ballistic missile is intercepted at its middle stage of boost phase,deriving an optimal guidance law which does not need the acceleration of interceptor is greater than the target' with the least energy.The two-dimensional closed-loop simulation results show that the overload of the interceptor is smaller if it meets the needs of the guide accuracy,so that it is useful in operational need.
