摘要	The weakness of current radiometric calibration methods for optical remote sensing instruments was analyzed to satisfy the precision needs of quantitative remote sensing and the data fusion coming from multi satellites. A standard transfer chain for radiometric calibration of optical sensing instruments with traceability was designed by taking a space cryogenic radiometer as a primary system for radiometric reference and the sun as the light source, which includes a solar monochromator, a transfer radiometer, a solar spectral irradiance monitor and a solar diffuser, etc. In radiometric calibration, the transfer radiometer and the solar spectral irradiance monitor were calibrated firstly by using spectral radiometric standards provided by the solar monochromator. And then the solar diffuser was calibrated by using the transfer radiometer. The radiometric standard was transferred to an imaging spectrometer for an earth observing standard, so that the radiometric standard could be used for inter calibration of other remote sensing instruments on other satellites. The analysis on the radiometric calibration for the standard transfer chain shows that the uncertainty of optical sensing instruments is 0.75%. It demonstrates that the proposed method is helpful for constructing calibration networks of remote sensing covering China in space and air and provides a technology foundation for developing space data quality assurance system parallel to the ground system of primary radiometric standards. , 2015, Chinese Academy of Sciences.
