We propose a method for direct diagnostics of a stochastic ionospheric radio channel. This method can recalculate probe signal characteristics into transmitted signal characteristics. We derive analytical equations of second-order statistical moments

We developed formalism for mathematical modeling of the effect of drift of chaotic irregularities of the electron number density on the spectral line width of a signal in the problem of sounding a randomly inhomogeneous plasma from the surface of a p

A semi-analytical fast computation method has been suggested for fluctuations of the direction of ray propagation in a chaotic space plasma with deterministic macro-scale irregularities of the refractive index. The method is based on the approximate

We examine the problem of transionospheric sounding with satellite radio signals at frequencies that are close to the edge of the radio transparency frequency range of the ionosphere. We derive asymptotic formulas for the group delay time of the tran

We examine the problem of small-angle scattering of radio waves experiencing total reflection from a randomly inhomogeneous layer of plasma. We consider the waves to be normally incident on the layer. To take into account the scattering peculiarities

This paper is concerned with the oblique propagation of decametric radio waves in the ionosphere with random electron density irregularities. Effective parameters are introduced for calculating the influence of irregularities on the wave field struct

A theoretical analysis is made of the chirp-ionosonde signal structure for the one- and two-hop propagation in a randomly inhomogeneous ionosphere. For the two-hop propagation, the influence of an additional wave scattering from ground roughnesses is
