摘　　要：超敏捷卫星动中成像模式相比传统推扫和敏捷机动模式,具有很大的效能提升和多种新型成像方式,但对空间相机在动中成像新模式下成像带来较大困难和挑战。首先分析超敏捷动中成像模式的原理特性,明确卫星快速机动过程中成像给空间相机对地观测带来的影响。然后开展动中成像下成像质量研究,以实际卫星可见光相机参数进行模拟分析,确立实现动中良好像质对速高比、积分级数的约束条件并进行参数优化设置。同时,对未来进一步提升动中成像下的成像质量提出攻关方向。研究成果对超敏捷卫星动中成像新模式下空间相机成像参数的确定具有指导意义,能够直接实现新模式下成像性能的大幅提升。The new mode of super agile satellite motion observation, which has various new observation mode is better than the traditional mode and the existing motion observation mode. However, it brings space camera study difficulties and challenges. In this paper, the principle and characteristics of the new mode of motion observation are analyzed, clarifying the effect of imaging on space camera observation during satellite rapid maneuvering stage. Then the observa- tion quality of motion observation is studied. The actual satellite visible light camera parameters are used to carry out the simulation analysis, and the constraints of achieving good image quality and moving speed ratio. At the same time, to further enhance the motion observation quality in the future, the key research direction is put forward. The results are of great significance for the determination of the imaging parameters of space camera in super agile satellite motion observation mode, which is beneficial to greatly improve the imaging performance under this new mode.
