针对传统的尾追方法在目标速度大于拦截器的速度时无法拦截目标的问题，建立拦截器与目标交会问题的三维运动模型，基于准平行接近原则对比研究适用于速度比小于1的迎击及前向拦截的速度比条件、有效拦截区域、需用过载、允许初始距离及导引特性。研究表明，两种方法的有效拦截区域取决于速度比及目标速度矢量前置角，对目标机动有类似的过载需求，但迎击的允许初始距离远大于前向拦截。仿真显示，迎击的交会时间及路径较前向拦截短，但过大的接近速率使其视线角速率过早发散，末段需用过载迅速增大。

The traditional tail?chase engagement is inefficacious when the velocity of a target is higher than that of an interceptor. To solve this problem,this paper establishes a three?dimensional kinematical model, making use of the head?on impact and the head?pursuit intercepting methods. The quasi parallel approach is used to examine the velocity ratio conditions, the largest interception region, the permitted initial distance, and the required overload. It is proved that, by approaching the predicted trajectory of the target or increasing velocity ratio, the impact region of interceptor can be significantly enlarged. The two methods have similar required overloads for maneuvering targets, but the permitted initial distance of head?on impact is much larger than that of head pursuit. The simulation shows both head?on intersection time and path are short compared with head pursuit, but the large head?on approaching velocity makes the LOS angular rate diffuse too early, which causes the required overload to increase rapidly in the end.
