HF Radar Activity in European Coastal Seas: Next Steps toward a Pan-European HF Radar
, 2017 High Frequency Radar (HFR) is a land-based remote sensing instrument offering a unique insight to coastal ocean variability, by providing synoptic, high frequency and high resolution data at the ocean atmosphere interface. HFRs have become invaluable tools in the field of operational oceanography for measuring surface currents, waves and winds, with ...

The processing of HF skywave radar signals
Proceedings of ICASSP '94. IEEE International Conference on Acoustics, Speech and Signal Processing, 2002This paper presents an overview of a significant and computationally demanding application of signal processing, viz. over-the-horizon radar (OTHR). The Jindalee Operational Radar Network is an integrated network of OTHRs which depend heavily for their performance, in both air and surface mode, on signal processing.

Ionospheric probing with an HF radar
Electronics & Communication Engineering Journal, 1989The Jindalee over-the-horizon (OTH) radar is designed primarily for extended air defence surveillance of Australia's northern coastline. It achieves its long-range capability by employing ionospheric reflection. This use of the ionosphere allows the radar to have a powerful secondary role in remote sensing because information about the ionosphere can ...

Rijkswaterstaat's interest in HF radar
IEEE Journal of Oceanic Engineering, 1986In this paper an explanation is given of Rijkswaterstaat's need for hydrological and meteorological information. The present means to gather this information are described together with their limitations. Future developments in the field of HF narrow-beam groundwave radar systems are indicated and some recommendations are given for the design of an ...

HF Ocean Radars in Ship Navigation
2018 IEEE 27th International Symposium on Industrial Electronics (ISIE), 2018Phased HF ocean radar technology is being widely used for surface current mapping in coastal waters, and the WERA radar produces gridded maps of surface currents and wave heights. These data can be put into existing AIS ship navigation messages to provide Aid to Navigation information to ship's bridges in coastal waters.

The development of a 26MHz pulsed Doppler radar system for remote sensing of ocean surface conditions is described. This radar obtains Doppler spectra of echoes from ocean waves within the range 10-40 km from the shore. From these Doppler spectra it is possible to estimate oceanographic parameters such as sea state, wind speed, wind direction, radial ...

HF radar detection of tsunamis
Journal of Oceanography, 2006This paper demonstrates that HF radar systems can be used to detect tsunamis well before their arrival at a coastline. We solve the equations of motion and continuity on the ocean surface using models to simulate the signals produced by a tsunami approaching the east U.S. coast.

A Proposal for an Operational HF Radar
1963Abstract : In response to the request of 7 March 1963 from the Director of Defense Research and engineering a radar system is proposed for the primary purpose of surveillance and tracking of aircraft within the USSR and the secondary purpose of detection of missile and ESV launchings.
