摘　　要：将弹头-目标相对运动关系分解为纵向平面和侧向平面内的相对运动关系,对非自旋弹头的制导问题进行了研究.为了保证非自旋弹头打击地面目标时的脱靶量和末端落角同时满足要求,提出了一种变结构制导律,该制导律在滑模面设计中同时包含了脱靶量和末端落角两种因素.采用指数趋近律方法来分别设计了纵向平面和侧向平面内的变结构制导律.仿真结果表明,所提出的变结构制导律不仅保证了脱靶量指标,而且使非自旋弹头以期望的末端落角命中目标,有效地提高了对目标的毁伤强度.The relative moving geometry of warhead with target was separated into vertical plane geometry and lateral plane geometry.The guidance problem of a non-spinning warhead was researched.A variable structure guidance law was proposed in order to ensure that both miss-distance and terminal angle can meet demands when a non-spinning warhead hit a ground target.Both miss-distance and terminal angle are comprised in the sliding mode design of this guidance law.The variable structure guidance laws of vertical plane and lateral plane are designed by the exponential reaching law.The simulation results show that not only miss-distance demand is guaranteed,but also a non-spinning warhead hit a target with desired terminal angle is made by the proposed variable structure guidance law,and its destroying intensity is increased effectively.
