Improving the efficiency of methods and means for suppressing unauthorized speech recording
Autor: A.N. Oleynikov, V.A. Pulavsky, I.N. Chigirev
Publikováno v: Radiotekhnika. :156-161
The article analyzes the effectiveness of suppressing an unauthorized recording using acoustic, electromagnetic and ultrasonic countermeasures. It is shown that acoustic, electromagnetic and ultrasonic counteraction without a priori knowledge of the

Estimation of efficiency of counteraction to photographic reconnaissance and video recording by the method of infrared hiding
Autor: V.D. Kukush, A.N. Oleynikov, N.А. Dibrova
Publikováno v: Radiotekhnika. :149-156
The photographic reconnaissance is the most widespread and effective method of getting information by the visual-optical channel. Reconnaissance facilities such as video- and photo cameras are accessible, multifunction devices which provide an opport

Publikováno v: Journal of Atmospheric and Solar-Terrestrial Physics. 69:2257-2264
Internal gravity waves (IGWs) over Kharkiv (49°30′N, 36°51′E) have been studied by using an automatic goniometer of a meteor radar (AG MR), with its antenna directed to the East. The AG MR carries out Doppler measurements of the radial drift ve

On the day-to-day wind and semidiurnal tide variations at heights of the mid-latitude summer mesopause: Zonal wavenumber estimations and its consequences, case-study in 1998
Autor: E. G. Merzlyakov, B.L. Kashcheyev, A.N. Oleynikov, A. H. Manson, Ch. Jacobi, Nicholas J. Mitchell, I. N. Fedulina, Yu.I. Portnyagin
Publikováno v: Journal of Atmospheric and Solar-Terrestrial Physics. 67:535-551
This work presents an analysis of spectra and estimations of zonal wavenumbers for mean wind and semidiurnal tide amplitude oscillations observed during July–September 1998 by 3 meteor radars and one MF radar. A number of mean wind and tidal amplit

Publikováno v: Journal of Atmospheric and Solar-Terrestrial Physics. 66:539-565
A network of 15 northern hemisphere radars has been used to measure horizontal winds in the mesosphere and lower thermosphere during the PSMOS campaign of Summer 1999. The radars are sited at latitudes ranging from 21°N to 75°N and longitudes from

Publikováno v: Journal of Atmospheric and Solar-Terrestrial Physics. 63:1017-1031
In July and August 1998, co-ordinated measurements of winds in the mesosphere/lower thermosphere region were carried out using meteor radars at Obninsk (Russia), Kharkov (Ukraine), Shrivenham (UK), and the low-frequency windprofiler at Collm (Germany

Autor: A.N. Oleynikov, B.L. Kashcheyev
Publikováno v: Journal of Atmospheric and Terrestrial Physics. 56:1197-1207
The coherent pulse Meteor Automatic Radar System (MARS) based at Kharkov (49°30′N, 36°51′E) was used to measure zonal winds in the altitude range 80–105 km in the period from November 1986 to December 1990. It was found that, for the greater
