The measurement of ocean waves and surface currents with a nautical radar is based on the spatial and temporal structure analysis of radar images of the sea surface. These radar images are generated by the interaction of HH-polarized electromagnetic waves with the sea surface ripples at grazing incidence. In these radar images the sea surface is visible as… (More)

Images generated by a common ship's navigation radar contain wave information. Digital techniques allow rapid acquisition and processing of such data. Since the radar is looking at extreme grazing angles, effects like diffraction and shadowing dominate the backscatter mechanism. As a consequence, no reliable backscatter model is available that allows… (More)
This work presents the estimation of wave field properties derived from X-band marine radar measurements taken close to coastal locations, where the wave fields are affected by the finite water depth conditions. The work is focused on the detection of individual waves and their related characteristics, such as the estimation of the local and instantaneous… (More)
