Abstract: A new tow-component Gaussian model is presented on the basis of the comparative analysis of the impact of wind speed on sea clutter average reflectivity described by existing international models. Based on the measured sea clutter data of VV polarization at low grazing angles collected by a L-band radar at the yellow sea of china, the model was validated with precision analysis. The relationship between the model parameters and grazing angle is analyzed and the fitting parameters of the model is given. According to the results of data analysis, the proposed model can well capture the trend of the sea clutter amplitude with wind speed. This model is important for design of radar systems and radar sea clutter prediction.
