Ionospheric Electron Content Effects on Earth-Space Radio Propagation. A Review.

Abstract

Radio waves when traversing the ionosphere undergo various types of signal degradation due to the nonhomogeneous characteristics of the medium. In this paper, the propagational effects such as group time delay, angular bending, phase and Doppler frequency shift, rotation of the plane of polarization and dispersion resulting from the presence of ionization along earthspace transmission paths are reviewed. The phenomena are described and assessed in terms of frequencies in the VHF range and above. The various techniques for the measurement of the ionospheric ionization are briefly discussed. (Author)
