Abstract

HF ocean surface radar technology has now developed to a point where permanently installed monitoring systems are being used for planning and operational purposes in several countries. In Australia and New Zealand there have been research and development systems but, apart from the defence sector, there have been no installations for monitoring for commercial benefit or long-term research projects. This is now changing. HF radar systems are now available commercially. The technology has a proven reliability in the mapping of surface currents, and is showing good results for wave and wind parameters. There are three conceptual approaches to HF radar systems which are quite fundamentally different and each of which will give best results under certain constraints and commercial needs. The three approaches are all available commercially. This paper reviews the HF ocean radar concept and outlines the benefits of each approach. We also map out a plan for the way in which this technology might develop in Australia. There are obvious beneficiaries in having local monitoring systems; for those in coastal engineering, management and leisure activities. There are also benefits in providing quality data in near real time to data networks like that run by the Bureau of Meteorology, and the Australian node of the Global Ocean Observing System: OZGO0S.
