  • Abstract
    Cross radiometric calibration is an effective method of no-ground-site calibration of remote sensors through building the relationship between the radiance of the reference sensor with higher radiometric accuracy and the experimental sensor, which can avoid the disadvantages of ground-site calibration — higher cost and longer update cycle of calibration coefficients. In this paper, the visible and near-infrared spectral bands of HJ-1B/CCD1 are cross-calibrated through the Ray-Matching method (RM) using the corresponding bands of Aqua/MODIS with higher radiometric accuracy and the TM image at a similar time is used to validate our results. Compared with the results by the coefficients of the satellite, the cross-calibration results by RM method are desirable and the error is acceptable, showing higher accuracy and effectiveness.
