RISUncertainty Estimates for SeaSonde HF Radar Ocean Current Observations
Publisher: American Meteorological Society
Abstract: HF radars typically produce maps of surface current velocities without estimates of the measurement uncertainties. Many users of HF radar data, including spill response and search and rescue operations, incorporate these ...
Direction Finding and Likelihood Ratio Detection for Oceanographic HF Radars

Evaluating Radial Current Measurements from CODAR High-Frequency Radars with Moored Current Meters
Publisher: American Meteorological Society
Abstract: The performance of a network of five CODAR (Coastal Ocean Dynamics Application Radar) SeaSonde high-frequency (HF) radars, broadcasting near 13 MHz and using the Multiple Signal Classification (MUSIC) algorithm for direction ...
Measurement of Antenna Patterns for Oceanographic Radars Using Aerial Drones
Publisher: American Meteorological Society
Abstract: new method is described employing small drone aircraft for antenna pattern measurements (APMs) of high-frequency (HF) oceanographic radars used for observing ocean surface currents. Previous studies have shown that accurate ...
Measuring Antenna Patterns for Ocean Surface Current HF Radars with Ships of Opportunity
Publisher: American Meteorological Society
Abstract: F radars measure ocean surface currents near coastlines with a spatial and temporal resolution that remains unmatched by other approaches. Most HF radars employ direction-finding techniques, which obtain the most accurate ...
Interpretation of Coastal HF Radar–Derived Surface Currents with High-Resolution Drifter Data
Publisher: American Meteorological Society
Abstract: Dense arrays of surface drifters are used to quantify the flow field on time and space scales over which high-frequency (HF) radar observations are measured. Up to 13 drifters were repetitively deployed off the Santa Barbara ...
