Since several years, High Frequency (HF) Over-The-Horizon (OTH) radar is used to measure océanographie parameters, such as currents, waves, and wind direction over large areas up to 200 km off the coast. Cost effective low power systems transmitting less than 50 Watts have been developed, e.g. the WERA (WEUen RAdar), and are now commercially(More)
—High-Frequency (HF) radars are operated in the 3-30 MHz frequency range and have been used for several decades now. Sky-wave systems are able to keep large areas under surveillance, e.g. the whole northern coast of Australia. Some of these systems have caused severe interference to other radio services like the Russian " Woodpecker ". Currently, a network(More)
—Besides the well known microwave radar systems mainly used in navigation, surveillance, and control applications, High-Frequency (HF) radars gain increased attention during the last decades. These HF radars are operated in the 3-30 MHz frequency range and due to ground-wave or sky-wave propagation provide over-the-horizon (OTH) capabilities. Many of these(More)
High-frequency (HF) surface wave radars provide a unique capability to detect targets far beyond the conventional microwave radar coverage but also could contribute to the development and improvement of Tsunami Early Warning Systems. This paper describes the simulation of tsunami related signatures observed by HF radar at long ranges in case of a tsunami(More)
