文章对国内外星载超光谱成像系统的应用状况进行了归纳,重点对其应用特点和关键技术进行了总结。在此基础上阐述了基于小卫星平台的超光谱成像系统的技术优势,探讨了利用小卫星姿轨机动灵活和可组成分离异构星座的特点,来实现星载超光谱系统对地实时成像以及解决海量数据处理和传输等关键问题的可行性,并着重对研制适应小卫星平台的集约型超过光谱成像载荷关键技术进行了分析。为建立星载对地“光学实时光谱识别系统”(ORASIS)提供参考。
The article summarizes the application status of the domestic and foreign spaceborne hyperspectral imaging systems, and focuses on the application features and key technologies. Based on this, the advantages of the hyperspectral imaging system based on the small satellite platform are expounded, and the characteristics of using satellite orbit movability and separation of isomeric constellations are discussed to realize real-time imaging of the spaceborne hyperspectral system and Solve the feasibility of the key issues such as mass data processing and transmission, and emphatically analyze the key technologies of developing the intensive over-imaging load that is adapted to the small satellite platform. It provides a reference for the establishment of satellite-borne “Optical Real-time Spectrum Recognition System” (ORASIS).
