Analysis of Refractive Effects on Mid-Latitude SuperDARN Velocity Measurements
(Virginia Tech, 2014-10-27)
First time ionospheric refractive index values have been determined at mid latitudes using frequency switched SuperDARN plasma convection velocity estimates. Previous works have found a disparity between high latitude ...
Large-scale observations of the spatial and temporal dynamics of quiet-time Sub-auroral Polarization Streams using SuperDARN HF Radars
(Virginia Tech, 2013-09-25)
The Sub-Auroral Polarization Stream (SAPS) is a narrow, intense and persistent westward (sunward) ionospheric convection flow channel observed equatorward of the auroral electron precipitation boundary, predominantly on ...
Design of Software Defined Radio for SuperDARN Radar
(Virginia Tech, 2019)
Software defined radio (SDR) is a rapidly developing field enabled by continuing improvements in digital electronics. Software defined radio has been used extensively in communication systems due to its flexibility and ...
Analysis of the Effect of the August 2017 Eclipse on the Ionosphere Using a Ray-trace Algorithm
(Virginia Tech, 2019-08-05)
The total solar eclipse over the continental United States on August 21, 2017 offered a unique opportunity to study the dependence of the ionospheric density and morphology on incident solar radiation. Unique responses may ...
Dynamics of the geomagnetically disturbed ionosphere as measured by GPS receivers and SuperDARN HF radars
(Virginia Tech, 2012-12-07)
Total electron content (TEC) data measured from ground-based GPS receivers is compared to HF backscatter from ionospheric irregularities obtained by Super Dual Auroral Radar Network (SuperDARN) radars. We present the first ...
Ion-neutral coupling in the geomagnetically disturbed mid-latitude ionosphere as observed by SuperDARN HF radars and NATION Fabry-Perot Interferometers
(Virginia Tech, 2015-09-17)
The earth's ionosphere-thermosphere region is a coupled environment which is governed by interactions between the overlapping neutral constituents and ionospheric plasma. The mid-latitude thermosphere-ionosphere system is ...
