N2 - Doppler centroid frequency is an important parameter for Synthetic Aperture Radar signal processing, which is used to design a proper matched filter in azimuth domain. Doppler centroid is estimated from the received data. There are number of different algorithms for the Doppler centroid estimation presented in the literature. In all these algorithms, a general the Doppler centroid estimation is done for the whole data. Thus, some distortions occur in the final image away from the scene center for where the Doppler centroid is estimated. To overcome this problem, an alternative method for the Doppler centroid estimation, which is based on block processing, is presented. This method also takes advantage for saving time when the interested area is small.
