摘　　要：在视线旋转坐标系下建立拦截弹与目标的相对运动方程,分析采用纯比例导引律捕获高超声速目标的充分条件,并推导出在交接班处的最优拦截几何,即零控拦截流型。定性分析了拦截弹速度、高度、导引头特性以及末制导捕获条件等在中末制导交接班时所受到的限制,在此基础上定义了中末制导交接班窗口的概念,并介绍了交接班捕获窗口的影响因素、用途、特性以及计算步骤。以纯比例导引律拦截高速目标为例,定量描述了交接班捕获窗口和零控交接班区域,并通过数字仿真实验验证了交接班捕获窗口的合理性。The equations describing the relative dynamics was established by using a modified polar coordinate.The capture region of the typical guidance law for intercepting the hypersonic target was derived,and the optimal intercept geometry which is the zero effort miss steering was derived.The missile speed,the missile height,the characteristics of seeker and terminal capture region were analyzed.Then,the influence factors,application,features of handover window and calculation flow were analyzed.Taking the pure proportional navigation guidance law as an example,the mid-course and terminal guidance handover window and the zero effort interception handover region were described quantitatively.Finally a simulation was performed to verify the feasibility of the handover window.
