针对航天遥感器进行辐射定标工作的定标精度评估时,并没有形成统一计算方法的问题,文章对工作在不同谱段遥感器的多种辐射定标精度计算方法进行了实例计算与研究。研究结果表明定标精度计算结果一般同具体的定标点选取相关。文章进而提出在比较不同遥感器辐射定标精度时需要明确精度计算的约束条件,这样才能增加精度对比的横向可比性,也能为客观的评价辐射定标工作提供更好的参考。
In order to evaluate the accuracy of calibration of radiometric calibration of aerospace remote sensors, a unified calculation method is not formed. The calculation and calculation examples of a variety of radiometric calibration accuracy of remote sensors operating in different bands are calculated and studied. The results show that the results of calibration accuracy are generally related to the selection of specific calibration points. In addition, the article puts forward that it is necessary to define the constraints of accuracy calculation when comparing the radiation calibration accuracy of different remote sensors so as to increase the horizontal comparability of accuracy comparison and provide a better reference for the objective evaluation of radiation calibration.
