Abstract

Three physical models for the microwave polarimetric brightness temperature of the sea surface are reviewed and compared. Two of these models are based on the composite surface theory, but use slightly different forms for the sea surface spectrum. The third model is based on a small slope approximation. All models are shown to predict similar zeroth, first, and second harmonic azimuthal variations of sea brightness and to show reasonable agreement with empirical results. However some discrepancies exist that is examined.
