Using the fixed calibration field with automatic observation equipment and sharing the other satellite's moving targets fields, a multi-sensor cooperative radiometric calibration method is proposed to improve calibration frequency. This method is developed based on the spectral flatness of the gray-scale tarps and the consistency of observation phase, geometry and field of the multi-sensors on the same platform. The radiance relationship model between the multi-spectral camera and the high resolution panchromatic camera is established, and then the cooperative radiometric calibration of the multi-spectral camera is realized by the high resolution panchromatic camera. The synchronous experiment results of Mapping Satellite-1 show that the radiance relationship model is universal, the relative difference between cooperative and site radiometric calibration coefficient of the multi-spectral camera is less than 5.3%, and the cooperative radiometric calibration precision is less than 5%. Compared with the site radiometric calibration, the same calibration precision is obtained while the calibration efficient is improved.
