Multipath Smearing Suppression for Synthetic Aperture Radar Images of Harbor Scenes

IEEE Access, 2019
Due to the periodic and non-periodic variations in the sea surface, smearing is caused by the multiple paths between the sea surface and man-made objects in synthetic aperture radar images of harbor areas. This smearing can cover real targets and lead to
