History of the Super Dual Auroral Radar Network (SuperDARN)-I: pre-SuperDARN developments in high frequency radar technology for ionospheric research and selected scientific results [PDF]
Part I of this history describes the motivations for developing radars in the high frequency (HF) band to study plasma density irregularities in the F region of the auroral zone and polar cap ionospheres.

Noncontact assessment for fatigue based on heart rate variability using IR-UWB radar
Physical fatigue can be assessed using heart rate variability (HRV). We measured HRV at rest and in a fatigued state using impulse-radio ultra wideband (IR-UWB) radar in a noncontact fashion and compared the measurements with those obtained using ...

HF Radar Activity in European Coastal Seas: Next Steps toward a Pan-European HF Radar Network [PDF]
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 ...

A comparison of satellite scintillation measurements with HF radar backscatter characteristics [PDF]
We examine the correspondence between high latitude ionospheric scintillation measurements made at 250MHz with the occurrence of 10MHz HF coherent radar backscatter, on 13 and 14 December 2002.

Mapping Wind Directions with HF Radar
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.

Spatiotemporal evolution of radio wave pump-induced ionospheric phenomena near the fourth electron gyroharmonic [PDF]
On 12 November 2001, the European Incoherent Scatter (EISCAT) high-frequency (HF) radio wave transmitter facility, operating in O-mode at 5.423 MHz with 550 MW effective radiated power, produced artificial optical rings which appeared immediately at ...

Validation of HF Radar Measurements [PDF]
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?
