Abstract

High-precision calibration and processing of optical remote sensing satellites is a necessary condition for obtaining all kinds of remote sensing observation products, and it is the basis for all kinds of remote sensing observation products to be fully and effectively applied. Radiometric calibration is to establish the quantitative relationship between the output value of each detector of the remote sensor and the corresponding actual ground radiation brightness. In this paper, an on-orbit yaw calibration method based on satellite yaw of 90 degrees is proposed, including the processing of yaw data and the acquisition of relative radiation calibration coefficient. Based on the data of hyperspectral detector of terrestrial ecological carbon monitoring satellite, the experimental results show that this method has a good effect on the relative radiation correction of hyperspectral detector, and the stripe noise of the original image has been well removed, which lays a foundation for the subsequent quantitative research and application of hyperspectral data.
