| 摘 要： | 针对空间轨道拦截作战模式,提出了一种拦截预警的计算方法.推导了求解轨道交点位置的表达式,然后结合拦截卫星的末端威胁距离给出了判断拦截是否发生的地心距判据和时间差判据,最后通过仿真算例验证了交点表达式以及判据的正确性,并讨论了拦截卫星的威胁距离与时间差门限的关系.

| Abstract: | Based on the space interception mode,a computation method to warn the interception event was proposed in this paper.The expressions for solving the state of the orbital intersection point were derived from the orbital kinetic equations with the geometric method.And then,the distance criterion and time criterion were obtained considering the threat sphere of the interceptor.Finally,the validity of the criterion was verified through the simulation and the relation between the threat distance and time criterio... |
