Specific features of the propagation of frequency modulated radio signals in the ionospheric plasma in the presence of local inhomogeneities

Abstract

Abstract The features of the propagation of frequency-modulated radio signals reflected from the anisotropic ionosphere containing local inhomogeneities of the electron concentration are investigated. On the basis of the Hamilton-Lukin bi-characteristic method, mathematical modeling of vertical sounding ionograms was carried out both in the case of propagation of an ordinary wave and in the case of propagation of an extraordinary wave. The results of numerical simulation are presented.
