• Borealis: An Advanced Digital Hardware and Software Design for SuperDARN Radar Systems 

      McWilliams, K.A.; Detwiller, M.; Kotyk, K.; Krieger, K.; Rohel, R.; Billett, D.D.; Huyghebaert, Devin Ray; Ponomarenko, P. (Journal article; Tidsskriftartikkel, 2023-02-17)
      The Borealis radar system is a hardware and software upgrade to the conventional Super Dual Auroral Radar Network radar system, which has been used since the early 1990s. The conventional system has hardware and software that is aging, and many components are no longer supported. Limitations of the conventional system limit radar and data techniques for scientific discovery. Using software defined ...
    • Determination of the Azimuthal Extent of Coherent E-Region Scatter Using the ICEBEAR Linear Receiver Array 

      Huyghebaert, Devin Ray; McWilliams, Kathryn A.; Hussey, Glenn; Galeschuk, Draven; Chau, Jorge L.; Vierinen, Juha (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-03-07)
      The Ionospheric Continuous-wave E-region Bistatic Experimental Auroral Radar (ICEBEAR) is a VHF coherent scatter radar that operates with a field-of-view centered on 58°N, 106°W and measures characteristics of ionospheric E-region plasma density irregularities. The initial operations of ICEBEAR utilized a wavelength-spaced linear receiving array to determine the angle of arrival of the ionospheric ...
    • The Distribution of Small-Scale Irregularities in the E-Region, and Its Tendency to Match the Spectrum of Field-Aligned Current Structures in the F-Region 

      Ivarsen, Magnus Fagernes; Lozinsky, Adam; St-Maurice, Jean-Pierre; Spicher, Andres; Huyghebaert, Devin Ray; Hussey, Glenn C.; Galeschuk, Draven; Pitzel, Brian; Vierinen, Juha (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-04-16)
      We associate new data from icebear, a coherent scatter radar located in Saskatchewan, Canada, with scale-dependent physics in the ionosphere. We subject the large-scale icebear 3D echo patterns (treated as 2D point clouds) to a data analysis technique hitherto never applied to the ionosphere, a technique that is widely applied in cosmological red-shift surveys to characterize the spatial clustering ...
    • The future of auroral E-region plasma turbulence research 

      Huyghebaert, Devin Ray; Billett, Daniel; Chartier, Alex; Chau, Jorge L.; Hussey, Glenn C.; Hysell, David L.; Ivarsen, Magnus Fagernes; Mesquita, Rafael L. A.; Rojas, Enrique; Vierinen, Juha; Young, Matthew (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-12-15)
      The heating caused by ionospheric E-region plasma turbulence has documented global implications for the energy transfer from space into the terrestrial atmosphere. Traveling atmospheric disturbances, neutral wind motion, energy deposition rates, and ionospheric conductance have all been shown to be potentially affected by turbulent plasma heating. Therefore it is proposed to enhance and expand ...
    • ICEBEAR-3D: A Low Elevation Imaging Radar Using a Non-Uniform Coplanar Receiver Array for E Region Observations 

      Lozinsky, Adam; Hussey, Glenn; McWilliams, Kathryn; Huyghebaert, Devin Ray; Galeschuk, Draven (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-02-19)
      The Ionospheric Continuous-wave E region Bistatic Experimental Auroral Radar (ICEBEAR) has been reconfigured using a phase error minimization and stochastic antenna location perturbation technique. The resulting 45-baseline sparse non-uniform coplanar T-shaped array, ICEBEAR-3D, is used for aperture synthesis radar imaging of low elevation targets. The reconfigured receiver antenna array now has ...
    • Investigating Spatial and Temporal Structuring of E-Region Coherent Scattering Regions Over Northern Norway 

      Huyghebaert, Devin Ray; Chau, Jorge L.; Spicher, Andres; Ivarsen, Magnus Fagernes; Clahsen, Matthias; Latteck, Ralph; Vierinen, Juha-Pekka (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-09-26)
      Recently, it has been shown that the Spread Spectrum Interferometric Multistatic meteor radar Observing Network radar system located in northern Norway is capable of measuring ionospheric E-region coherent scatter with spatial and temporal resolutions on the order of 1.5 km and 2 s, respectively. Four different events from June and July of 2022 are examined in the present study, where the coherent ...
    • Multiple E-Region Radar Propagation Modes Measured by the VHF SIMONe Norway System During Active Ionospheric Conditions 

      Huyghebaert, Devin Ray; Clahsen, Matthias; Chau, Jorge L.; Renkwitz, Toralf; Latteck, Ralph; Johnsen, Magnar Gullikstad; Vierinen, Juha (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-05-10)
      Multiple propagation modes between different bistatic radar links were measured during the operations of a very high frequency (VHF) 32.55 MHz radar system in northern Norway. The Spread Spectrum Interferometric Multistatic meteor radar Observing Network (SIMONe) Norway system detected meteor trails, direct transmitter to receiver signal propagation, over-the-horizon signal propagation from the ...
