中文说明：该程序包涵盖了二维空间导弹拦击目标问题的各种仿真模拟程序，其中导弹和目标模型均采用低保真度模型，即假设导弹和目标均为质点运动模型，程序包中讨论了各种工况因素对导弹导引律设计的影响和注意事项。求解器采用二阶龙格库塔方法，以保证求解精度。制导拦截仿真包括开环和闭环两种，其中开环仿真采用真实信息生成导引指令；闭环仿真采用滤波器提供的状态估计生成导引指令。
English Description：
The package covers the two-dimensional space missile volley goal for a variety of simulation programs, including missile and target models are used in Lo-Fi models, where missile and target for particle motion model packages discussed in the different working conditions and influence factors on missile guidance law design considerations. Solver using the erjielonggekuta method, in order to ensure accuracy. Guided-intercept simulation including both open-loop and closed-loop, open-loop simulation using real information guidance command; status estimates generated using filter for closed-loop simulation-guided instruction.
