星载微光成像仪辐射定标与资料应用研究进展

Research Progress on Radiation Calibration and Data Application of Spaceborne Low-Light Imager

随着光电技术的发展,低照度条件下的微光成像及其应用成为近年来的研究热点之一。对于定量遥感的气象海洋环境卫星,微光成像仪辐射定标与资料应用的研究也受到普遍的关注。以目前国际上最具代表性的微光成像仪载荷VIIRS/DNB为例,系统阐述了夜间不同月相条件下传感器绝对辐射定标与气象海洋环境资料应用等技术问题的研究进展,以期为相关科学研究和实际工程应用提供有用信息。

With the development of optoelectronic technologies, low-light imaging and its application under low illumination conditions have become one of the research hotspots in recent years. For the meteorological and marine environment satellites of quantitative remote sensing, the research on radiometric calibration and data application of low-light imagers has also received widespread attention. This paper takes the most representative low-light imager load VIIRS/DNB in the world as an example, and systematically illustrates the research progress on the sensor absolute radiation calibration and data application in the meteorological and marine environment under different moon phases at night, in order to provide useful information for scientific research and practical engineering applications.
