In-orbit Radiometric Calibration and Quantitative Application for Civil Remote Sensing Satellite Payloads

This paper summarizes the characteristics of China's civil satellite payloads and the research status of radiometric calibration,and ascertains the calibration method flow that suits China's civil satellite payloads.We perform the calibration and validation of civil satellite by using above mentioned methods.The retrieval algorithm of land surface property parameters,such as reflectance and temperature,are researched based on the civil satellite remote sensing data.At last,a application demonstration of land surface products is performed.The result shows that the method stipulated in the paper is appropriate to in-orbit calibration and validation of satellite payloads,and the calibration coefficients are accurate for quantitative application,the demonstration result based on our country remote sensing data is very well.
