The numerical calculation of wave-fields, reflexion coefficients and polarizations for long radio waves in the lower ionosphere. II

Abstract

The characteristics of radio waves of low and very low frequency reflected from numerical models of electron density and collision frequency are calculated by the methods described in the preceding paper (Pitteway 1964). The models used are based on those found by cross-modulation experiments and approximate to those likely to be found in the ionosphere. The effects of changing the models are investigated with the object of developing methods of solving the inverse problem of deducing the ionization structure from the experimental data on long and very long wave propagation. The relations between the computed and observed characteristics are examined in a preliminary way.
