THE SIMULTANEOUS MEASUREMENT OF IONOSPHERIC ELECTRON DENSITIES BY CW PROPAGATION AND RF IMPEDANCE PROBE TECHNIQUES
Abstract
The Aerobee-Hi rocket NASA 4.07 obtained vertical electron density profiles in the ionosphere simultaneously by the Seddon CW propagation technique and by an RF impedance probe technique. The experimental goal was to assess the performance of the RF probe against the accurate values from the CW method. It was concluded that, with allowance for the positive ion sheath around the rocket, the RF impedance probe can yield reliable values of electron density. These values were obtained from changes in the capacitive part of the probe's impedance. Small, apparently anomalous changes in the resistive part were also observed. (Author)
