Autor: Vladimir Kurkin, V. A. Ivanov, V. V. Shumaev, V. E. Nosov, V. P. Uryadov
Publikováno v: Scopus-Elsevier
We present a review of materials related to a chirp ionosonde and its application in the ionospheric research. The principle of operation of an ionosonde radiating a continuous signal with linear frequency modulation is described. The chirp-ionosonde

We present the results of observations of round-the-world (RTW) signals by the Russian chirp-sounder network in 1997-1999. The frequency-time intervals of the RTW propagation with minimum attenuation are determined. Using numerical simulations of HF

On the chirp-signal structure along the oblique-incidence ionospheric sounding path
Autor: M. V. Tinin, N.T. Afanasiev, V. P. Grozov, V. E. Nosov
Publikováno v: Journal of Atmospheric and Solar-Terrestrial Physics. 63:11-19
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

The March 9, 1997 solar eclipse ionospheric effects over the Russian asian region
Autor: G.A. Zherebtsov, V. F. Smirnov, V. E. Nosov, Vladimir Kurkin, A. P. Potekhin
Publikováno v: Advances in Space Research. 27:1437-1440
The ionospheric response to the total solar eclipse of 1997 March 9 was considered on the database of some ionosondes (longitudinal chain) and Irkustsk incoherent scatter radar. The deviations of ionospheric parameters as a consequence of solar eclip

We analyze theoretically the structure of a chirp-ionosonde signal for the cases of one- and two-hop propagation in the randomly inhomogeneous ionosphere. For the case of two-hop propagation, wave scattering by the rough ground is taken into account.

Publikováno v: SPIE Proceedings.
Analysis of the behavior of main ionospheric parameters allows us to study the physical processes in the ionosphere and develop empirical and semi-empirical the ionosphere models (IRI) with applications to the various geo- and radio-physical problems

Publikováno v: Eighth International Symposium on Atmospheric and Ocean Optics: Atmospheric Physics.
The Irkutsk Incoherent Scatter (IS) radar is a unique facility in Russia, designed for geophysical and radio- probing investigations of the upper atmosphere. The range of problems tackled using the radar is quite extensive. Having a high potential an

Use of long-term prediction in automatic vertical-incidence ionogram processing
Autor: V. E. Nosov, V. P. Grozov, G. V. Kotovich
Publikováno v: SPIE Proceedings.
Of decisive importance in diagnosing the ionospheric channel is the use of vertical-incidence sounding (VS) ionograms. The ionogram processing problem involves identifying characteristic points corresponding to actual signal modes, followed by approx
