Estimating Surface Currents Across Fronts Using Synthetic Aperture Radar

Abstract

Description of a forward model for predicting radar cross section modulations across a tidal current front consisting of published components for: (1) surface currents across a tidal current front; (2) solving the wave action balance equation to determine modulations in wave spectra across the front; and (3) generation of RCS from the modulated wave spectra. The model is applied to Synthetic Aperture Radar imagery collected during the ONR Mobile Bay experiment and compared to hydrodynamic model results provided by Woods Hole Oceanographic Institute.
