Optical remote sensing satellites are an important part of the current Earth observation technology, and with the development of space technology and the diversification of application requirements, their imaging models are becoming more and more diversified. The overall development trend of optical remote sensing satellites is to achieve ultra-large width and ultra-high spatial resolution. In the face of the growing demand for large-scale and high-timed Earth observation in the region, rotational geography has gradually become a new model and has been gradually studied and developed. The rotating ultra-large wide imaging optical satellite adopts the conical scanning earth observation technology system of area scan camera, realizes ultra-large area observation through conic scanning, and designs widearea search imaging and encryption imaging modes in key areas, which has the characteristics of wide-area, highresolution and multi-angle imaging. The degradation information of rotational imaging optical satellite images is difficult to accurately estimate and the spatiotemporal characteristics are complex, and the ground imaging process is composed of satellite flight motion and turntable rotation, and in order to compensate for the image shift effect in the imaging process, the satellite is equipped with a fast reflection compensation mirror and the detector rotation mechanism for realtime motion compensation, which makes it difficult to accurately construct and calculate the image degradation model. In order to accurately obtain the mechanism and process information of image quality degradation at the focal plane, the accurate perception and modeling method of dynamic imaging degradation information is studied, and key technologies such as progressive information fusion based on overall weighting of bidirectional filtering, separation and spatiotemporal modeling of high and low frequency degradation information based on Fourier model, and single-sided image compensation restoration based on degenerate spatiotemporal model are broken, and distortion-free high-quality images in rotational maneuvering mode are obtained, which lays a theoretical and algorithmic foundation for the design and data processing of rotating imaging optical satellites.
