多光谱扫描仪的星上辐射定标系统

THE SPACEBORNE RADIANT CALIBRATION SYSTEM OF MULTISECTRAL SCANNER

文中简要阐述目前辐射定标的三方面工作,飞行前的绝对定标,飞行中的星上定标以及飞行中利用辐射校正场的绝对定标。比较详细地阐述多光谱扫描仪星上定标系统的关键技术及采取的技术途径,介绍了内定标系统和太阳定标系统。

This paper synopsises the radiant calibration technique in three fields: the absolute calibration before flight, on-board calibration in flight and the absolute calibration applying radiant calibration field in flight. Key techniques of the calibration system of multispectral scanner are states in details, the internal calibration system and the solar calibration system are introduced, too.
