摘　　要：针对目前天基对地动能武器打击范围求解过程中未考虑地球自转,地球扁率和地球引力摄动因素的问题,提出了有限推力作用下打击范围的求解方法。建立了基于混合法的天基对地动能武器转移轨道优化模型和大地经纬度坐标系下打击范围求解模型。仿真计算以处于近地轨道的天基对地动能武器为研究对象,结果表明了天基对地动能武器转移轨道优化模型和打击范围求解模型的可行性。打击范围的求解为后续更加直观地判断目标点是否处于打击范围内打下基础,丰富了空间作战的相关理论。In order to solve the problem of striking range without considering the earth rotation, the earth flattening factors and the terrestrial gravitational perturbation, the solving method for striking range of the space-to-ground kinetic weapon under the limited thrust engine was studied. Both the transfer trajectory optimization model based on the hybrid method and the solving model of the striking range with the longitude and latitude as coordinates under the limited thrust engine were established. The space-to-ground kinetic weapon in low earth orbit was taken as the objective, and results show that the models proposed were feasible to solve the transfer trajectory and striking range. The solving of striking range lays a foundation for judging whether the target point is in the striking range more directly and enriches the theory of space operation.
