摘要
基于冲量变轨理论,建立了天基动能拦截器通过一次变轨机动拦截目标的轨道机动模型,提出了攻击区和威胁区的概念,并给出了确定攻击区和威胁区的数值搜索算法。通过仿真计算,分别对不同的拦截时间和机动能力约束条件下攻击区和威胁区进行了仿真分析,结果表明,利用本算法能够方便地得到动能拦截器的攻击区和目标的威胁区,为拦截的实现提供必要的决策条件。
Based on impulse orbit -transfer theory, the interception model of the space based kinetic interceptor through only one orbit maneuver is set up, the concepts of the attacking area and the threatening area are put forward, and numerical methods are presented to determine these two areas. A lot of simulations are done to compute the attacking area and the threatening area under different restrictions of interception time and kinetic interceptor maneuverability. The simulation results indicate that this method, which is used to determine the attacking area of the interceptor and the threatening area of the target, provides the necessary prerequisite for the realization of space interception.
