Abstract :
A synthetic aperture radar (SAR) data reformatting approach named Doppler Keystone transform (DKT) is proposed to correct the range migration of the moving target. By combining the DKT and the Doppler phase compensation methods, the moving target can be well imaged in high signal-clutter-ratio (SCR) case. Moreover, the DKT-based algorithm is suitable for parallel implementation.
