High-resolution airborne synthetic aperture radar
(SAR) systems are very sensible to deviations of the aircraft from
the reference track. In high-resolution imagery, the improvement
of range resolution increases the difficulty of implementing range
cell migration correction (RCMC), while a wider synthetic aperture
increases the cumulative time of motion errors which will
affect the image quality. To enable accurate motion compensation
in image processing, a high-precision navigation system is needed.
However, in many cases, due to the limit of accuracy of such systems,
motion errors are hard to be compensated correctly, causing
mainly the resolution decrease in final image
