ANTENNA IMPEDANCE PROBES IN HIGHLY DISTURBED IONOSPHERES.
Abstract
This report details instrumentation developed for measurement of electron densities in a highly disturbed ionosphere. The measurement determines by a standing wave technique, the RF impedance of thin cylindrical antennas immersed in the plasma of the ionosphere. The electron density can be deduced from the antenna impedance variations. A previously developed Standing Wave Impedance Probe was used at frequencies of 3 and 12 MHz in conjunction with a newly developed 300-MHz system. Instrumentation details including schematic diagrams of both systems are presented. The dual impedance probe system was included in the payload of an Honest John-Nike-Javelin III fired from Eglin AFB in a DASA Project 6.4 certification round. (Author)
