摘　　要：天基对地打击武器(SGKW)用于从太空对地面战略目标和高价值目标进行快速、准确地打击,是未来空间威慑和一体化作战的重要手段。对SGKW的作战轨道进行了建模分析,研究了SGKW的最优过渡轨道。采用遗传算法与经典优化方法相结合的组合优化策略求解轨道优化问题,结果表明,组合优化方法可以很好地克服传统优化方法的初值敏感问题,能够搜索到全局最优的轨道。Space-to-Ground Kinetic Weapon（SGKW） is a kind of new concept weapon. It is mainly used to strike the tactic and high worth ground targets quickly and exactly form the outside space. On the basis of fight application analysis, the optimal transfer orbit of SGKW is researched. Genetic algorithm is applied with classical optimization method to solve the problem of low thrust orbit optimization. Simulation results show that using genetic algorithm to solve trajectory optimization problems can overcome the issue of initial value sensitivity by traditional optimization methods and the global optimum orbit can be found by genetic algorithm.
