摘要：

The on-orbit absolute radiometric calibration of satellite remote sensing payloads is crucial to ensuring the radiometric consistency of products from different sources and improving the inversion accuracy of high spatial resolution products. The traditional site calibration method based on manual synchronous measurement is limited by the imaging, surface and atmospheric measurement conditions at the time of satellite overpassing, which is difficult to meet the needs of correcting the radiometric performance change accurately during the life cycle. In this paper, according to the characteristics of large viewing angle observation of the wide width sensor onboard Gaofen6 satellite (GF-6/WFV), a time series absolute radiometric calibration method for the GF-6/WFV sensor with automatic radiometric calibration site is proposed. The proposed method not only can track the trend of satellite payload radiation performance by significantly increasing the frequency of on-orbit calibration, but also can give the calibration results with uncertainties. Based on proposed method, 41 of frequencies automatic radiometric calibration results of GF-6/WFV sensor were calculated from August 2019 to October 2021, and the traceability uncertainty of the calibration results was better than 5% (except for the 7th band). The trend analysis of the time series calibration results shows that the annual variation of the radiometric calibration coefficients of the GF-6/WFV sensor are from 1.10% to 4.59%. In addition, the high-precision in-orbit satellite payloads MODIS and Sentinel-2/MSI are used as reference to cross validate the GF-6/ WFV sensor’s calibration results. And, the averaged absolute relative differences of the cross validation were between 2.12% to 6.09% respect to the bands 1 to 4 of GF-6/WFV sensor. The proposed method in this paper can realize the time-series on-orbit absolute radiometric calibration of the GF-6/WFV sensor and its radiometric performance trend change monitoring during the whole life cycle, which can effectively support the production of high spatial resolution remote sensing products and improve the quantitative application level of Chinese remote sensing data. © 2023 National Remote Sensing Bulletin.
