HF Radar Activity in European Coastal Seas: Next Steps toward a Pan-European HF Radar Network [PDF]

Frontiers in Marine Science, 2017
High Frequency Radar (HFR) is a land-based remote sensing instrument offering a unique insight to coastal ocean variability, by providing synoptic, high frequency and high resolution data at the ocean atmosphere interface. HFRs have become invaluable tools in the field of operational oceanography for measuring surface currents, waves and winds, with ...

The CALYPSO HF Radar Data Interface

, 2013
Within the ambit of the CALYPSO project, a network of HF-radars with installations on the northern coast of the Maltese Islands, and on the southern Sicilian coast is intended to provide real-time sea surface currents in the Malta Channel. This paper describes the web interface developed to provide users with viewing, selection and downloading of the ...

Coverage Area Analysis of Combined Sky-Wave and Surface-Wave Monostatic High Frequency Radar

IEEE Access, 2019
High-frequency combined sky-wave and surface-wave monostatic radar (CSSM-HF RADAR) is a new type of radar system inspired by the skywave components of high-frequency surface-wave radar (HFSWR). The new type of radar uses the combined propagation paths of

Extraction of the significant wave height from synthetic HF radar data acquired on a floating platform

IET Radar, Sonar & Navigation, 2023
The usual procedure for extracting ocean surface information from data acquired from a high‐frequency surface wave radar transmitting from a floating platform is to first compensate for the motion of the antenna in the acquired motion‐contaminated ...

Validation and Evaluation of a Ship Echo-Based Array Phase Manifold Calibration Method for HF Surface Wave Radar DOA Estimation and Current Measurement

Remote Sensing, 2020
Shore-based phased-array HF radars have been widely used for remotely sensing ocean surface current, wave, and wind around the world. However, phase uncertainties, especially phase distortions, in receiving elements significantly degrade the performance ...
