The invention provides a space target in-motion push-broom imaging attitude maneuver method. A spacecraft is adopted to perform a push-broom imaging task on a space moving target, so that the method has good practicability. Aiming at the problem that there is no maneuvering method for attitude compensation during space moving target push-broom imaging, the invention provides a method for carrying out imaging moment preliminary screening according to imaging conditions and then carrying out push-broom imaging along a given direction by adopting a constant attitude angular velocity, so that active attitude push-broom imaging of a space rapid motion cooperative target is realized. According to the method, different imaging requirements can be met by changing the threshold value of the imaging screening condition, the push-broom speed and the integral time can be changed by adjusting the speed coefficient, and therefore better space target imaging quality is obtained.

    本发明提出一种空间目标动中推扫成像姿态机动方法,采用航天器对空间运动目标的推扫成像任务有很好的实用性。本发明方法针对空间动目标推扫成像时还没有姿态补偿的机动方法问题,提出一种根据成像条件进行成像时刻初筛,然后采用恒定姿态角速度沿给定方向进行推扫成像的方法,实现了对空间快速运动合作目标的主动姿态推扫成像。本发明方法可以通过改变成像筛选条件的阈值满足不同的成像需求,可以通过调整速度系数改变推扫的快慢和积分时间,从而获取更好的空间目标成像质量。
