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.
Within the EU MAST-2 project SCAWVEX (Surface Current And
Wave Variability EXperiments),
work on HF-radar related techniques, algorithms and models, has been performed.
The University of Hamburg developed a new HF radar WERA (WEllen
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.
HF radar will be an important tool for coastal management and harbour
authorities. Integrated systems using radar measurements and 3-d models
are to be developed for this purpose and can play an important role within
EuroGOOS. Wave and current data from the SCAWVEX experiments will be presented
to demonstrate the value of radar systems of this kind.
This work has been funded by the European Commision DG XII within the MAST-2
programme, project SCAWVEX, ct94-0103.
