Vicarious radiometric calibration and validation of CBERS02B CCD data
CBERS02B 卫星CCD 相机在轨辐射定标 与真实性检验

A comprehensive calibration and validation experiment of CBERS02B CCD was performed by the Center for National Spaceborne Demonstration at the Gongger site on October 12, 2007 in order to support the quantitative application program of CBERS02B data and improve the quantitative application level of CBERS02B data. The reflectance-based method was used to obtain CCD calibration coefficients for the quantitative application program of CBERS02B CCD data. The validation of the calibration coefficients was carried out at Dunhuang test site to verify reliability of the coefficients. It was shown that the vicarious calibration results were in good agreement with the measurement values. It was concluded that the calibration coeffi-cients was highly reliable.
