Improved entropy-based autofocus correction for synthetic aperture radar
Autofocus is an essential step in order to obtain the well-focused synthetic aperture radar image. Compared to the non-parametric autofocus, the parametric way is not subjected to the prominent targets so much. Entropy is widely used in parametric autofocus. It is sensitive to the clutter and not a...
