High-frequency (HF) surface-wave (SW) radar systems have demonstrated their capability to capture the signals from seismic and non-seismic tsunami events using the estimation of surface current changes. Several ocean radar systems, operating in the u

Abstract A high-frequency (HF) ocean radar system is a shore-based remote sensing system to simultaneously monitor ocean surface currents, waves and wind far beyond the horizon. The system operation is based on electromagnetic wave propagation coupli

A review is given of the impact that HF radars are having on the management of coastal hazards. Maps of surface currents can be produced every 10–20 minutes which, in real time, improve navigation safety in restricted areas commonly found near port

High frequency (HF) radars operate at radio frequencies between 3 and 30 MHz, where electromagnetic waves have the ability to propagate along the ocean surface and therefore to obtain information beyond the horizon. All the information measured by a

An important property of the high-frequency (HF) band (3–30 MHz) is the unique ability of HF signals to propagate over long distances and to illuminate the Earth's surface beyond the horizon. Historically, over-the-horizon (OTH) HF radar systems we
