Digital Ionospheric Sounding in the Arctic.

Abstract

Digital techniques applied to ionospheric sounding measure new parameters of the reflected radio signals, like Doppler shift, wave polarization, and incidence angles. The Digisonde on-board AFGL's Airborne Ionospheric Observatory was modified to incorporate a discrete Fourier transform for each frequency-range bin. Goose Bay vertical ionograms were scaled in terms of 23 parameters. The monthly median curves of the most important ionospheric parameters for the period March 1975 to February 1976 are presented in the report.
