A method for suppressing sea surface clutter, based on the characteristics of sun glint, is proposed. The proposed method is built on an infrared polarization radiation model of the dynamic sea surface. Based on the time-domain polarization characteristics of sun glint in a dynamic sea scene, a method for taking linearly polarized images at different analyzer angles over fixed intervals is used to suppress sea clutter by using the minimum operation. Experimental results show that the proposed method can effectively improve the contrast between a target and its background. Following simplification, this method can also provide a streamlined sea clutter suppression method with obvious results.
