“环境-1号”A星高光谱成像仪飞行定标

In-flight Absolute Calibration of the HJ-1A HSI

文章针对高光谱成像仪(HSI),详细介绍了HSI的飞行绝对辐射定标方法,分析了影响HSI飞行定标精度的各种因素。并利用2008年12月6日HSI过河北白洋淀时的同步观测数据验证了定标精度,结果表明绝对定标系数合理可靠。

This paper presented the in - flight absolute calibration method of the HJ - 1A HSI, and all the factors affecting the radiometrie calibration accuracy were also analyzed. Finally, the synchronization HSI data, covering Baiyangdian of Hebei province on Dec 6th, 2008, was used to verify the absolute calibration accuracy and the result showed that the calibration coefficient was valid and reliable.
