HF radars are a unique and powerful tool for measuring surface currents. They provide an unparalleled window into the spatial variations of near-surface currents. But oceanographers who are more accus...
Experience With Shipborne Measurements of Surface Current Fields by HF Radar
Shipborne Measurements Surface Current Fields HF Radar
2015/8/10
Oceanographic research using HF radar techniques started in Germany in 1980 by adopting NOAA's CODAR (Coastal Ocean Dynamics Applications Radar), which has originally been introduced by Barrick et al....
A fractal model for the sea state bias in radar altimetry
fractal model sea state bias radar altimetry
2009/11/13
The Kirchhoff approximation is used to determine the sea state bias in radar altimetry. A weakly nonlinear model of the sea waves is used to derive the joint moments of two different points separated ...
Intensity of convective motions in marine atmospheric boundary layer retrieved from ocean surface radar imagery
Intensity of convective motions marine atmospheric boundary layer ocean surface radar imagery
2009/11/9
The paper focuses on the occurrence and development of coherent structures observed in the atmosphere above ocean under natural conditions. Microwave imaging radars are suggested as data take instrume...
Dekameter Radar Observations of Ocean Wave Growth and Decay
Dekameter Radar Observations Ocean Wave Decay Growth
2009/2/16
Immediately following the passage of polar fronts that produced strong winds blowing away from Galveston Island and into the Gulf of Mexico, we used scattered LORAN-A radio waves, together with observ...
Directional Wave Spectra Measured with the Surface Contour Radar
Directional Wave Surface Contour Radar
2009/1/15
The Surface Contour Radar is a 36-GHz computer-controlled airborne radar which generates a false-color coded elevation map of the sea surface below the aircraft in real-time, and can routinely produce...
The Fine-Structure of Nearshore Tidal and Residual Circulations Revealed by H.F. Radar Surface Current Measurements
Ocean Surface Current Radar Residual Circulations Nearshore Tidal
2009/1/7
Using the Ocean Surface Current Radar (OSCR) developed by the Rutherford–Appleton Laboratory (UK), 30 days of synoptic hourly surface current vectors were obtained for 84 locations within a nearshore ...
Radar Returns from the Sea Surface—Bragg Scattering and Breaking Waves
Radar Returns Breaking Waves Sea Surface—Bragg Scattering
2009/1/6
Recent ideas on the structure of the equilibrium range of wind-generated ocean waves are applied to the question of radar backscattered returns from the sea surface. It is shown that the backscatterin...

2008/12/27
An X-band marine radar on Windmill Hill, Gibraltar, was used to monitor the propagation of internal waves in the Strait of Gibraltar during March, April, and June 1986. Surface roughness features of t...
Study of Polarization Differences in Ku-Band Ocean Radar Imagery
Ku-Band Ocean Radar Imagery vertical/vertical horizontal/horizontal
2008/12/12
Radar returns from the sea surface can be represented as the sum of two contributions from Bragg scattering and from individual breaking events. This representation is used to analyze polarimetric rad...
