Abstract:

The long-term goal of this project is to develop a forward model that predicts the Synthetic Aperture Radar SAR signature of Non-Linear Internal Waves NLIWs under a range of environmental conditions. The objectives of this project are to understand, quantify and model the factors that influence the SAR signature of internal waves IWs using in situ and remote measurements. To accomplish this we will determine the factors that impact the both the surface roughness and the corresponding radar backscattering cross section. Two factors that influence surface roughness that have not been included explicitly in earlier models for predicting the SAR signature of IWs are compound modulation and breaking waves. We are developing models for both of these contributions.
