摘　　要：以临近空间高超声速飞行器X-51A为研究对象,基于X-51A超燃冲压发动机参数,通过估算其机动能力,提出巡航段拦截的制导方案,并分析了拦截弹可拦截锥角与速比的关系。为满足直接碰撞杀伤需求,论证了轨控直接力的使用方式、引入时机。最后,基于临近空间目标的雷达隐身和红外辐射特性,采用平台式红外导引头设计方案,并基于截获概率和制导精度约束,提出了对导引头帧频、分辨率及视场的指标要求。Taking near-space hypersonic vehicle X-51A as research object,its maneuverability is estimated based on parameters of X-51A's scramjet,then guidance scheme of intercepting in cruise phase is put forward,and the relationship between Interception angle and velocity ratio is analyzed.For meeting the requirements of direct impact,the way of using rail control direct force and it's timing introduction are demonstrated.Last,by comparing radar stealth and infrared radiation of the near space target,a design scheme of platform type infrared seeker is put forward,and based on acquisition probability,guidance accuracy,seeker's frame rate,resolution and field of view are proposed.
