Doppler rate is an important parameter in synthetic aperture radar (SAR) imaging. Incorrect Doppler rate would cause great degradation of image quality. In this paper, by estimating the Doppler rate in high-contrast scene first, and then utilizing the fact that Doppler rate is inversely proportional to range, the Doppler rate in low-contrast scene is estimated indirectly and effectively.
