To validate on-orbit radiometric performance of PMS sensor onboard SJ-9A satellite, and obtain accuracy absolute radiometric calibration coefficients of PMS, a cross-calibration method between GF-1 WFV and SJ-9A PMS sensor based on homogeneous land surface targets is established. This paper describes the theory of cross-calibration and characteristic of homogeneous field targets, and analyzes the parameters and spectral bands responsibility between PMS and WFV. Then, the cross-calibration of WFV and PMS is performed based on historical measurements data of Dunhuang sites and simultaneously observation images of two sensors on August 2, 2013. The influence factors and uncertainty of cross-calibration between WFV and PMS are discussed. The results indicate that this method for cross-calibrating PMS is doable and the spectral band matching factors is stabile and has lower sensitivity with field reflectance changing. The uncertainty of cross-calibration results of PMS is less than 5.24%. This study production can lay the foundation for on-board radiometric properties evaluation and quantitative application of SJ-9A satellite, and supply reference to cross-calibration between Chinese satellite remote sensors.
