Abstract

Regular monitoring and assessment on radiometric performance of satellite sensors is necessary for the quantitative remote sensing application and development. HJ satellite was launched by China on 2008, which was put forward to achieve dynamic monitoring of environment and disasters, also need to monitor radiometric performance and provide stable and reliable calibration coefficients timely. In this study, Terra/MODIS data were used to calibrate HJ-1A CCD camera by cross-calibration technique in Dunhuang radiometric calibration site. Total thirteen HJ -1A CCD images were utilized, the 6s model was used to estimate the spectral matching factors. Finally, this study obtains long-term HJ-1A CCD calibration coefficients from 2009 to 2012. Results show that each band of HJ-1A CCD is varying degrees of degradation after HJ satellites launched 5 years later. This study is helpful to obtain high accuracy and reliable calibration coefficients and monitor radiometric performance of HJ-1A CCD.
