Abstract

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 algorithm can achieve high resolution image formation in large scene. The azimuth resolution is less than 2m.
