Abstract
Recent studies have revealed that the residual range
migration effects of synthetic aperture radar (SAR) imagery
smears induced by moving targets can exhibit complicated
shapes that are not limited to that of parabolas. This letter
demonstrates that automatic focusing methods can remove such
range migration effects by estimating and compensating for phase
errors directly in the radar video phase history domain. This
approach is validated using measured Ku-band SAR clutter data
containing buildings and foliage.
