Rapid Variations in Electron Density Profiles in the Ionosphere Detected with the IZMIRAN High-Speed Ionosonde

Autor: V. Yu. Kim, A. V. Branitskii, V. P. Polimatidi

Publikováno v: Geomagnetism and Aeronomy. 60:63-79

The article presents a new technique for the measurement of rapid variations in electron density in the ionosphere based on the rapid obtainment of vertical sounding ionograms. The new technique uses broadband pulse signals, the spectrum of which can

Publikováno v: 2011 XXXth URSI General Assembly and Scientific Symposium.

Fast Doppler measurements technique of observation of small-scale, magnetic field aligned inhomogeneities produced in the Ionosphere by powerful HF radio waves is developed. This technique is based on evaluation of “momentary” Doppler shift of re

Autor: G. G. Vertogradov, V. Yu. Kim, I. V. Krasheninnikov, V. P. Polimatidi, V. P. Uryadov

Publikováno v: 2011 XXXth URSI General Assembly and Scientific Symposium.

Experimental results of HF radio waves scattering from artificial irregularities induced by "Sura"heating facility FMCW (chirp sounding) method as a diagnostic tool are presented. Elimination of the disturbed region of the ionosphere was performed fr

Publikováno v: Radiophysics and Quantum Electronics. 28:655-665

This paper reports on strong attenuation of probe radio waves that have been observed when the waves propagate through the ionosphere as it is being disturbed by an intense radio wave. Experimental results are compared with theory. The effect observe
