Abstract

This paper proposed a new method to estimate the ship azimuth velocity in TerraSAR-X data based on the minimum-entropy criterion. The moving targets in synthetic aperture radar images are blurred because of the mismatch of the desired signal of stationary targets. Applying the image entropy, a simple parameter to evaluate the extent of the defocusing, the azimuth velocity can be recovered through searching the minima of the entropy curves. The signal models of moving targets are analyzed and their behaviors in SAR images are deduced in this paper. Experiment results show that our method for estimating ship azimuthal velocities in TerraSAR-X data has high precision and is robust.
