Paper Abstract

Uncompensated phase errors presented in synthetic-aperture-radar (SAR) data have a disastrous effect on SAR image quality. To estimate and compensate phase errors, a new method is presented based on the time-frequency distributions of the range-compressed SAR signal. Robust phase errors estimates are obtained by utilizing range redundancies The processing results of the simulated data show the validity of the proposed method.
