摘要

Abstract: A new radiometric calibration system was developed for the prelaunch calibration of an optical sensor (OPS) on the Japanese Earth Resources Satellite (JERS), to be launched in 1992. OPS consists of eight bands from 520 nm to 2400 nm. The primary standard of the calibration system was fixed-point blackbodies of copper, silver, zinc, lead and tin. The transfer standard was two variable temperature blackbody furnaces used at temperatures from 232$DGR@C to 1362$DGR@C. The spectral radiances were transferred to a large internally illuminated integrating sphere with an inner diameter of 1 m and an aperture 280 mm in diameter. The OPS was calibrated against the large integrating sphere. Uncertainty of the spectral radiances of the variable temperature blackbody furnaces was estimated to be $POM@1.3% and that of the large integrating sphere to be better than $POM@3%.!
