摘　　要：针对空间对地遥感观测任务对遥感器高分辨率和灵活性的需求,文章提出并介绍了智能空间光学载荷技术。所研制的新型载荷系统的设计思想是将微型高精度星敏感器、MEMS陀螺仪、高分辨率光学相机进行一体化设计,全面提高在轨成像时相机姿态实时性测量精度及各组件数据深耦合性。应用实时定姿定位、动态像速匹配及像差追踪校正,图像非盲反卷积等自主研究开发的最新理论和技术成果,实现遥感器在轨智能化高分辨率成像。根据智能载荷的技术特点开展了相关原理样机标定和测试技术的研究。In this paper, technologies of the smart spacebome optical payload in modem high resolution space remote sensing mission are introduced, which are aimed at the requirements of high resolution and flexibility space imaging missions in future. The main idea for the smart payload prototype concerns the integrated design of high-precision star sensor, MEMS gyroscopes and high-resolution optical camera, to improve the accuracy of real-time attitude measurement as well as the data deep coupling. The smart payload can perform high-resolution agile imaging which is founded on the technologies such as integrated fixed-posture positioning, dynamic image velocity matching and aberration correction in tracking mode, image non-blind deconvolution and the latest theoretical and technological achievements in other independent research and development. Furthermore, specific techniques for smart payload calibration and testing are presented.
