英文摘要	Oceanic emission and scattering model is critical in remote sensing wind vector using passive polarimetric microwave radiometer. This paper presents a detailed analysis of a simplified Two-Scale Model for ocean surface polarimetric microwave emission, and investigates the extent to which varying ocean surface length scales contribute to brightness temperature zeroth and second azimuth harmonics. The Two-Scale Model can be expressed as a weighting function M-0,M-2 multiply ocean surface curvature spectrum C-0,C-2. This implies a simple way to investigate the effect of ocean surface parameters and curvature spectrum on ocean emission separately. It is found that ocean waves with wavelengths both comparable to and much greater than the electromagnetic wavelength can contribute to these harmonics, depending on the value of the ocean surface spectrum in these length scales. It is obvious that brightness temperature predictions will also differ more significantly because of the spectral model chosen.
