Abstract
Geosynchronous circular SAR (GeoCSAR) is a novel system combined with GeoSAR and the Circular SAR (CSAR). The daily track of GeoCSAR is an inclined ellipse, while we divided the total aperture into several sub-apertures. Based on 2-D SAR image of sub-aperture we can observe the same place continuously. While the aperture is disturbed by perturbations and could not be approximated as a line. This paper discuss the precise imaging model of GeoCSAR, and simulates the corresponding raw data of point target and distributed target.
