Applications of HF Radar in Operational Oceanography

Abstract

About HF Radar

A High-Frequency (HF)-radar can be used to measure surface current fields and the spatial distribution of ocean wave directional spectra. The physical mechanism behind is backscattering from a moving rough surface. These radars are deployed along the coast and cover an area of up to 50 km x 50 km, which can be observed continuously at 10 minute intervals.   HF_SCATTER   Antennas
Within the EU MAST-2 project SCAWVEX (Surface Current And Wave Variability EXperiment), work on HF-radar related techniques, algorithms and models, has been performed. The University of Hamburg developed a new HF radar WERA (WEllen RAdar). The wave algorithm has been developed by the University of Sheffield, the current algorithm has been adopted by the University of Hamburg from their previous CODAR (COastal raDAR) system. The spatial resolution of WERA can be selected between 1.2 km and 300 m.   What is WERA   Photo WERA
