Abstract
The key problem of the imaging processing in geosynchronous earth orbit (GEO) SAR is the space-variance of the Doppler parameters, which will result in the defocusing with classical imaging algorithm. In this paper, a Modified Range Migration Algorithm (RMA) is proposed to overcome the space-variance of Doppler parameters by compensating the velocity change along the scene range direction. Furthermore the simulation results fully verify the effectiveness of derived algorithm after velocity compensation.
