This paper presents a nonlinear chirp scaling in processing monostatic and bistatic SAR data. When the effects of quadratic range migration are negligible, a time domain range cell migration correction can be applied. After the correction, the FM rates of targets confined in a range gate will differ from each other. A nonlinear chirp perturbation function can be applied to each range gate to equalize the targets' FM rates before azimuth compression
