Testing the Re-designed SuperDARN HF Radar and Modeling of a Twin Terminated Folded Dipole Array
The Super Dual Auroral Radar Network (SuperDARN) is an international collaboration of researchers interested in Earth's near-space plasma environment. This group uses high frequency (HF) radars and backscatter from magnetic field-aligned plasma irregularities to study space weather manifested in …
