N2 - Vehicle-borne synthetic aperture radar (SAR) has the advantages of flexible configuration, convenient deployment, and long endurance, making it an effective means for high-resolution imaging of space targets such as geosynchronous (GEO) satellites. Due to the long distance between the SAR platform and the GEO satellite, it requires extremely long synthetic aperture time to achieve high-resolution imaging. In this case, GEO satellite motion cannot be ignored, which causes defocusing in SAR imaging. To address this issue, this paper derived an accurate slant range model between the GEO satellite and the vehicle-borne SAR platform. Based on this, the impact of GEO satellite motion on SAR imaging and the impact boundary are analyzed. The accuracy of the slant range model and the impact boundary is verified through simulation.
