Mapping Wind Directions with HF Radar
Oceanography, 1997 BESIDES THE MEASUREMENT of ocean surface currents, high-frequency (HF) radar has also been demonstrated to be effective at measuring the wind direction at scales on the order of one to several kilometers and over areas of millions of square kilometers in the case of sky-wave HF radars (Georges et al.

Validation of HF Radar Measurements [PDF]
Oceanography, 1997 made? H F RADARS ARE A UNIQUE and powerful tool for measuring surface currents. They provide an unpa ra l l e l ed window into the spat ial var ia t ions of near-surface currents. But oceanographers who are more accus tomed to measur ing currents with instruments that actually get wet may reasonably ask how accurate can such remote measurements be made?

First-order Sea Clutter Modeling and Simulation of High Frequency Passive Radar
Leida xuebao, 2015 High Frequency (HF) passive radar is a typical bistatic radar, and the modeling and simulation of sea clutter in bistatic radar are worth researching for HF passive radar.

Introduction to Coastal HF Maritime Surveillance Radars
Polish Maritime Research, 2019 This paper presents the main technical characteristics and working performances of coastal maritime surveillance radars, such as low-power High-Frequency Surface Wave Radars (HFSWR) and Over the Horizon Radars (OTHR). These radars have demonstrated to be

Phenomena induced by powerful HF pumping towards magnetic zenith with a frequency near the F-region critical frequency and the third electron gyro harmonic frequency [PDF]
Annales Geophysicae, 2009 Multi-instrument observational data from an experiment on 13 October 2006 at the EISCAT/HEATING facility at Tromsø, Norway are analysed. The experiment was carried out in the evening hours when the electron density in the F-region dropped, and the HF ...

Space Surveillance with High-Frequency Radar
SensorsHigh-Frequency (HF) radar is well suited to the surveillance of low-earth-orbit space. For large targets, a small deployable HF radar is able to match the detection performance of much larger space surveillance radar systems operating at higher ...

Wave and tidal power measurement using HF radar
International Marine Energy Journal, 2018 The use of HF radar systems located on the coast to measure ocean surface waves and currents is reviewed. Examples are given showing temporal, spatial and directional variability in the wave and tidal power resource. HF radars are unique in being able to
