文章介绍了2004年CBERS-02星热红外波段绝对定标工作,结合野外试验情况和数据处理过程深入进行了不确定性因素分析(包括误差分析),并从亮温反演的角度分析定标精度,进而针对如何提高在轨卫星热红外波段绝对辐射定标的精度,进行了探讨。
In this paper, the absolute calibration of the CBERS-02 satellite thermal infrared band in 2004 is introduced. Based on field experiments and data processing, uncertainty analysis (including error analysis) is conducted in depth and the calibration is analyzed from the point of view of brightness temperature Accuracy, and then how to improve the orbit satellite thermal infrared band absolute radiation calibration accuracy, were discussed.
