Geosynchronous orbit synthetic aperture radar (GEO-SAR) has a good application prospect for its shorter repeat period and a wider swath compared to low Earth orbit SAR. Doppler characteristic of the echo is analyzed. The Doppler history varies frequently in space and approximates a high order signal. A back projection algorithm for high resolution GEO-SAR based on satellite-ground geometry model is preliminarily proposed. Steps of the algorithm are given. The simulation results indicate the… Expand
