In order to analyze the scattering characteristics of sea surface under high sea state, a complete scattering model of sea surface considering breaking wave is established in this study based on the refined facet scattering field model (RFSFM) and the scattering theory of breaking wave. On the basis of this model, the influence of breaking waves on the mono/bistatic SAR imaging of sea surface at HH and VV polarization is studied. The results show that with the increase in wind speed, the coverage of breaking wave increases obviously and the consideration of breaking wave has a good correction for the scattering coefficient at HH polarization under grazing incidence; however, for VV polarization, the effect of breaking wave is very small.

Sea surface temperature (SST) is a prerequisite for sea surface infrared imaging simulation. A temperature model suitable for seawater heat exchange is proposed based on the heat balance of air-sea interface and equations of fluid heat exchange. The model considers the air-sea heat transfer characteristics and influences of penetrating solar radiation in seawater. Effects of the solar radiation, sea surface wind speed and air temperature on SST are analyzed. Temperature model is also used to simulate the SST diurnal variation and compared with the measured values to verify the validity of the model. The results show that the model is useful for solution of sea surface transient temperature field and provides the basis for infrared imaging simulation of sea surface.
