Abstract

Considering the aging and radiation recession of satellite remote senors on-orbit, regular in-orbit calibration is essential to updating the calibration parameters and improving the data’s quantitative application level. This paper reviews the existing on-orbit radiometric calibration methods, and introduces famous radiation calibration fields around the world. Simultaneous ground measurement was carried out for the calibration of visible-near infrared bands of HJ-1B satellite. A comparison was made between the results of the experiment and the calibration parameters released along with environmental satellite images, which represents desirable validity and applicability. The calibration result determined the sensor recession and aging in in-orbit operation. Finally, reasonable proposals for the quantitative application of satellite data are given.
