A crucial problem in most airborne Synthetic Aperture Radar systems is the compensation of motion errors to prevent image degradation. If these errors are not corrected, some undesired effects will appear, such as loss of geometric resolution and radiometric accuracy, reduction of image contrast, azimuth ambiguities and strong phase distortions. In this paper we will work in the compensation of the motion errors for the hybrid experiment, this is, a combination of an airborne sensor with a spaceborne sensor.
