Wave and wind parameters from HF ocean radar

A sparse network of surface current and wave-capable HF radars is being established around the Australian coastline to produce quality controlled data into a public-domain archive under the umbrella of the Integrated Marine Observing System (IMOS). The phased array installations within the Australian Coastal Ocean Radar Network (ACORN) produce maps of significant wave heights, and wind directions, and under good signal-to-noise conditions, generate directional wave spectra. The radar installations are always made in matched pairs, spatially separated so that the beams formed by the phased arrays cross at a non-acute angle in the primary area being mapped; this gives the 2-D capability of each radar pair. Phased-array stations are installed at the Capricorn/Bunker Groups, QLD (Tannum Sands, and Lady Elliot Island); the entrance to the South Australian Gulfs, SA (Cape Wiles, Eyre Peninsula and Cape Spencer, Yorke Peninsula); Rottnest Area, WA (Port Beach, Fremantle and Guilderton); and Coffs Harbour, NSW (Red Rock and North Nambucca).
