Abstract
The paper proposes a new approach for automatic estimation of the Doppler rate during the SAR image formation process. The technique is based on the scaling property in the azimuth direction applied to chirp signals. The measurement of the scaling error between two processed images with low resolution is used to estimate the effective sensor velocity. The proposed method shows superior performance when compared to traditional autofocus techniques.
