Book excerpt: The frequency shift during reflection of radio waves from an ionospheric layer varying in time are considered. Plane stratified and spherically stratified isotropic layers are analyzed for oblique incidence of the radio wave as well as the anisotropic layer for vertical incidence. The method for the determination of the temporal variation of local electron concentrations from simultaneous measurements of frequency shift and group time delay in the ionosphere at two neighboring frequencies is described.

Book excerpt: In a computer experiment, a corrugated mirrolike reflection surface was made to move horizontally above a plane containing a pair of points representing a bistatic ionospheric radar. The reflection surface was synthesized by the superposition of sinusoidal cylindrical waves that were allowed to move in different directions. A search routine was developed to find the rays that pass through the pair of points and satisfy specular reflection conditions at the surface. Path lengths and their derivatives were computed. The resulting patterns are descriptive and predictive of the effects of wavelike ionospheric perturbations on radio signal characteristics. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: The study of very long-distance and around-the-world propagation of HF radio waves becomes more urgent in connection with the problems of long distance ground-based radio communications, communications with space crafts and satellites, satellite-to-satellite communications, around-the-world radar scanning, around-the-world sounding of the ionosphere, etc. At pre sent, these investigations have acquired particular interest because transmit ters which make it possible to intentionally modify the ionospheric properties by powerful radio waves have become available. In the case of radio wave propagation over comparatively small distances (about 3000 - 5000 km, one - two hops), in a first approximation, the iono sphere can be considered homogeneous in the horizontal direction. The radio wave propagation theory in a horizontally-homogeneous, i. e. , spherically symmetric ionosphere was developed with sufficient completeness as early as in the 1920-1940's by Appleton, Ratcliffe, Beynon, Booker, Martyn, and others. This theory is presented in detail in the well-known monographs by Ginzburg (1967), Bremmer (1946), and Budden (1961). Based on this theory, detailed methods for the calculation of radio paths, determination of field amplitude, and interpretation of vertical and oblique ionograms have been developed. All these methods are well-known and widely used in practice, see monographs by Al'pert (1974), Shchukin (1940), and Davies (1969). An altogether different situation takes place in the case of very long-dis tance multihop and around-the-world propagation.

Available in PDF, EPUB and Kindle. Book excerpt: This bibliography comprises a non-exhaustive compilation of over 1400 references to the world's literature in the ionosphere with special emphasis on its effect on reflection, refraction or propagation of electromagnetic waves. The frequencies involved are usually in the low frequency or long wave bands in contrast to those (UHF, VHF and SHF) involved in tropospheric propagation investigations although the pulsed technique at vertical or slant incidence makes use of a wide range of frequencies.
