On the dependence of radar signatures of surface current variations on the azimuthal radar look direction

Abstract

An improved two-dimensional composite surface model for the radar imaging of underwater bottom topography in tidal waters is presented. It accounts for the hydrodynamic modulation of the entire wave spectrum by surface current variations. The authors discuss the dependence of the resulting radar signatures on the radar frequency, polarization, incidence angle, and the azimuthal radar look direction. An interesting result is that the contribution of the normal traveling wave components to the radar backscatter is negative for all incidence angles at vertical and for steep incidence angles at horizontal polarization, while the contribution of parallel traveling waves is always positive.
