Sea surface topography reconstruction from X-band radar images
The paper deals with the feasibility study of the sea state monitoring starting from X-band radar images. The exploitation of radar images allows to achieve a global vision of the sea state compared to the local vision given by the usual sensors as the buoys. The processing approach is based on the formulation of problem as an inverse one where starting from the electromagnetic field backscatte...
متن کاملA Comparison between Drifter and X-Band Wave Radar for Sea Surface Current Estimation
This paper deals with exploitation of the wave radar system for sea surface current estimation in a coastal zone. In particular, we present the results of the processing of the radar data collected by an X-band marine radar installed in Capo Granitola site, which is located in the south-west part of Sicily, on 15 May 2015. The effectiveness of the data processing is analyzed by comparing the wa...
متن کاملEffect of Changes in Sea-Surface State on Statistical Characteristics of Sea Clutter with X-Band Radar
We have made observations of X-band radar sea clutter from the sea surface and sea-surface state in the Uraga Suido Traffic Route, which is used by ships entering and leaving Tokyo Bay, and the nearby Daini Kaiho Sea Fortress. We estimated the distributions of reflected amplitudes due to sea clutter using models that assume Weibull, Log-Weibull, Log-normal, and K-distributions. We then compared...
متن کاملDetermination Of Nearshore Wave Conditions And Bathymetry From X-Band Radar Systems
Proudman Oceanographic Laboratory (POL) deployed an X-band (9.8GHz, 3cm wavelength) marine radar during the European COAST3D field experiments in Teignmouth, UK. The study site is a complex three-dimensional tidal inlet. A sequence of 64 radar images was collected at time interval of 2.25s every hour. Although realistic-looking wave patterns are observed in the radar images, it is still unclear...
متن کاملWave Height Estimation from Shipborne X-Band Nautical Radar Images
A shadowing-analysis-based algorithm is modified to estimate significant wave height from shipborne X-band nautical radar images. Shadowed areas are first extracted from the image through edge detection. Smith’s function fit is then applied to illumination ratios to derive the root mean square (RMS) surface slope. From the RMS surface slope and the mean wave period, the significant wave height ...
