Analyzing the statistical property of polarization ratio of radar sea clutter provides a reference for radar detection. In this paper, statistical distributions of the amplitude and phase of polarization ratio for radar sea clutter are analyzed. The sea clutter amplitude distributions in horizontal and vertical polarization channels are analyzed with real sea clutter data at first. Based on this, statistical distributions of the amplitude of the polarization ratio are derived. Analysis results of real sea clutter data are coincident with the theoretical derivation of the distribution of polarization ratio amplitude for sea clutter and show that the distribution of polarization ratio phase approximates to Gaussian distribution.
