Abstract

In this paper, the reflectance-base method was adopted for the absolute radiometric calibration of HY-1 COCTS at China Dunhuang Calibration Test Site on July 16th, 20th and 23rd of 2002. and the background information was provided about the site condition of Dunhuang test site. At the same time, the BRDF correction due to the zenith angle of satellite was computed. Comparing the calibration results of this test with those of the pre-launch calibration, a good agreement at six channels is achieved except channel 1 (412 nm) and channel 2 (443 nm).
