2022-11-01 On-orbit absolute radiometric calibration of high resolution satellite optical sensor based on gray-scale targets doi:10.57760/sciencedb.06070 en Radiometric calibration in -flight is one of critical techniques for information quantification of optical satellite sensor. A calibration approach based on gray -scale targets has been presented. It substitutes the measured ratio of diffusion to global irradiance and atmospheric optical depth to the assumption of aerosol scatter. And the method could isolate the DN signal created by the targets from the response produced by background radiance sources, which simplify the calibration process. remote sensing; radiometric calibration; gray-scale targets xu wei wei PUBLIC https://creativecommons.org/licenses/by-nc/4.0/ dataset Science Data Bank
