The invention discloses a pulse maneuvering condition-based optimal track pursuit strike starting azimuth analysis method, which comprises the following steps of: setting pursuit two parties to pursuit on the same track surface, establishing a track coordinate system by taking the initial position of an escape spacecraft as an original point based on the track height and the initial relative distance between the escape spacecraft and a pursuit spacecraft, and setting the initial relative distance between the escape spacecraft and the pursuit spacecraft; determining the initial states of the escape spacecraft and the pursuing spacecraft; based on the initial states of the escape spacecraft and the pursuit spacecraft, a pulse pursuit game strategy solving method based on game tree search is adopted, and the relative distance under the optimal strategy is obtained; and the pursuit spacecraft starts pursuit from different starting orientations, and the relative distances of all orientations under the optimal strategy are compared to obtain the optimal pursuit starting orientation under the initial condition. According to the method, the influence of the limited action set of the pursuit spacecraft and the natural evolution of the spacecraft is considered, the optimal pursuit start orientation under the same orbit plane is obtained, and the research of subsequent orbit pursuit on initial position selection is facilitated.

    本发明公开了一种基于脉冲机动条件的轨道追逃最佳追击启动方位分析方法,包括:设定追逃双方同轨道面进行追逃,基于轨道高度和逃跑航天器与追击航天器的初始相对距离,以逃跑航天器初始位置为原点建立轨道坐标系,确定逃跑航天器和追击航天器的初始状态;基于逃跑航天器和追击航天器的初始状态,采用基于博弈树搜索的脉冲追逃博弈策略求解方法,得到最佳策略下的相对距离;追击航天器分别从不同的启动方位开始追击,比较所有方位在最佳策略下的相对距离,得到在该初始条件下的最佳追击启动方位。本发明考虑追逃航天器的有限动作集和航天器自然演化的影响,得到同轨道面下的最佳追击启动方位,有助于后续轨道追逃对初始位置选择的研究。
