Long distance propagation of HF radio waves
Abstract
The present work deals with a systematic description of the theory of radio wave propagation in a threedimensional inhomogeneous ionosphere. Consideration of the features of the actual horizontallyinhomogeneous ionosphere makes it possible to significantly simplify the problems of radio propagation and to derive the main relations of the adiabatic approximation theory. The sphericallysymmetric ionosphere is considered along with the horizontallyinhomogeneous ionosphere, regularities of very longdistance radio wave propagation in the ionosphere, the calculation of longdistance radio paths, radio wave scattering, nonlinear phenomena, radio wave propagation in the magnetosphere, the radio wave field distribution in connected waveguide ducts, analytical models of ionospheric parameters, and the wave theory of HF radio wave propagation in a horizontallyinhomogeneous ionosphere. Attention is given to very longdistance and magnetospheric propagation, longdistance oblique sounding, and signal fluctuations in the reception point.
