Abstract In this paper, based on polarization characteristics decomposition of full-polarization information processing, a novel method of detecting low observable targets within sea clutter at low grazing angle is proposed for the first time. Through analyzing the real full-polarization data, the polarization characteristic of sea clutter, described before, has been verified. The differences of polarization characteristics, after polarization characteristics decomposition, between pure sea clutter and the one including the small target have been compared, according to which a novel polarization characteristic, named Distance Between Entropy and Anisotropy (DBEA), is proposed. The detection result can be obtained after the new method based on the scattering mechanism difference of DBEA. It has been proved that the new way has good detection performance and strong robustness with more times random test and under more sea state levels.
