The quality of images obtained with a synthetic aperture radar (SAR) strictly depends on the platform trajectory measurement precision. A crucial point is that even expensive navigation systems often do not fulfill the accuracy requirements. This is especially critical for a high-resolution SAR imaging. In the paper a novel approach which can successfully handle the residual deviations is proposed.
