The invention discloses a natural evolution-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, determining the initial states of the escape spacecraft and the pursuing spacecraft; the initial states of the escape spacecraft and the pursuit spacecraft are substituted into a spacecraft orbit transfer equation for derivation, the relative distance between the pursuit and the escape after the orbit transfer time is obtained, and the optimal pursuit starting direction is derived; and solving the optimal pursuit start orientation by adopting a numerical solution method, and changing the transfer time to obtain the optimal pursuit start orientation under different transfer time. According to the method, the optimal pursuit starting orientation under the same orbit plane is obtained through derivation of the orbit transfer equation, and research on initial position selection of follow-up orbit pursuit is facilitated.

    本发明公开了一种基于自然演化的轨道追逃最佳追击启动方位分析方法,包括以下步骤: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;将逃跑航天器和追击航天器的初始状态带入航天器轨道转移方程进行推导,得到轨道转移时间后的追逃双方相对距离,并推导出最佳的追击启动方位;采用数值求解方法求解最佳追击启动方位,并改变转移时间,得到不同转移时间下的最佳追击启动方位。本发明通过轨道转移方程的推导,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。
