摘　　要：研究大气层外动能拦截器(EKV)拦截弹道的快速规划方法。在分析拦截弹拦截作战任务基础上,分析了陆基拦截弹(GBI)关机点处的位置、速度选择应该服从的主要约束条件;以拦截交会角最小为目标函数,建立了EKV拦截弹道反设计的优化模型,利用遗传算法和反向积分的方法搜索得到了EKV初始弹道6个弹道参数、3个约束条件的初始拦截弹道参数。仿真结果验证了本研究方法的正确性,亦表明在难以获得拦截弹真实弹道解算所需基础数据的情况下,采用本方法的工程反设计方法规划的EKV拦截弹道可在一定程度上接近真实弹道,能够满足导弹突防对抗仿真需要。Due to the need of studying midcourse penetration counter simulation, the quick design method of intercept trajectory layout about Exoatmospheric Kill Vehicle（EKV） was researched. With analyzing the combat mission of interceptor. The main restric condition that the missile＇s place and speed should obey in the cutoff of Ground Based Interceptor （GBI） was gave out. Take the minimum of intercept rendezvous an- gle as objective function, the optimal model of inverse design of intercept trajectory about EKV is established. Finally,six trajectory parameters of EKV initial trajectory and GBI initial parameters of three restrict condition are got by genetic algorithm and reverse integral method. The correctness of the strdying method is proved by the result of simulation. The method of inverse design offers a new method for missile penetration counter simulation.
