| Abstract: | Climate change monitoring and high resolution earth observation demand higher accuracy of absolute calibration for space optical sensors.This paper briefly discusses the progress and constrained factors of current radiometric calibration techniques.New calibration approaches and instrumentations such as hyperspectral and spectrally tunable reference light sources,and global calibration site network are introduced,and their applications are suggested. |
