show that the uncertainty of the calibration approach is less than 3.6%. The difference in calibration coefficient between the WDTMLR method and the reflectance-based method is less than 5.5%. Moreover, the difference between the reflectivity and radiance of ground object obtained by the satellite sensor and that of field measured value is less than 6%, which demonstrate the effectiveness of on-orbit radiometric calibration. The WDTMLR method can satisfy with the application requirements for high-precision on-orbit calibration in complex environmental conditions.
