Long Waves Influence on Polarization Ratio for Microwave Backscattering from the Sea Surface
The effect of slopes created by long waves on the resonance backscattering of microwave radio waves analyzed. The analysis is carried out within the framework of the Gaussian model of slopes distribution. The polarization ratio increases by approximately 10% as the wind speed increases up to 5 m/s if the sounding is performed along the direction of wind. If the sensing is accomplished across the direction of wind, as the wind speed tends to 5 m/s the polarization ratio increases to approximately 6%. The effect of the presence of long waves weakly depends on the incidence angle.
