Summary:
Some of the results of the recent field investigation of the radar backscattering from the sea surface are presented. The novelty of the experiment consists in the use of the stereo-photo imaging to extract information about the scattering surface along with direct radar measurements. The analyzed data were the synchronized samples of the radar cross-sections and corresponding 3-D scattering surfaces with measured small-scale roughness properties. Great impact of active breaking waves on the radar return is observed directly, yielding the value of the radar cross-section of the breaking mass of water. The popular two-scale composite model of the sea surface is shown to underestimate radar return in Ka-band even in absence of the active breaking wave. Strong correlation between the radar cross-section and signatures of the microscale breakers suggests that the curvature effects are important to explain experimental data.
