Документ The F2-layer parameter variations during spring equinox 2013, according to the Kharkiv and EISCAT incoherent scatter radars data(НТУ "ХПІ", 2014) Zhivolup, T. G.The investigations of temporal variations of the electron density in the F2-layer maximum, ion and electron temperatures in the mid-and high latitudes during the 2013 year spring equinox are conducted. The features of the temporal variations of the parameters of the F2-layer in Kharkiv and Tromsø during the spring equinox are revealed. It was established that during the spring equinox changes amplitude electron and ion temperatures in the ionosphere over Tromsø less than the amplitude of temperature changes of electrons and ions in the ionosphere over Kharkiv on the entire time interval of joint observations from 07:00 to 24:00 UT.Документ Measurement of the geomagnetic field in the ionosphere using radar methods(НТУ "ХПІ", 2014) Skvortsov, T. A.; Emelyanov, L. Ya.; Fesun, A. V.; Belozerov, D. P.A new method for measuring the geomagnetic field in the ionosphere by the integrated use of vertical sounding radar (ionosonde) and incoherent scatter radar, its capabilities and features of the technical implementation, as well as the first results of an experimental test are considered.Документ Refinement of the incoherent scatter radar constant(НТУ "ХПІ", 2014) Shapovalova, D. V.; Pulyayev, V. А.Examined a variant of the software for procedure realization for comparing the level of noise at the input of the incoherent scatter radar, order to improve its constants without using information from the ionospheric station.Документ Technology and equipment for fast oil and adsorbent regeneration with application of high-power HF electromagnetic field(НТУ "ХПІ", 2014) Rymar, S. I.The method of adsorbent drying by electromagnetic field is presented. Technology and equipment for fast oil and adsorbent regeneration with application of high-power HF electromagnetic field are shown.Документ Travelling ionospheric disturbances over Kharkiv, Ukraine, accompanying the operation of EISCAT heater facility(НТУ "ХПІ", 2014) Panasenko, S. V.; Rietveld, M. T.; La Hoz, C.; Domnin, I. F.We have detected the travelling ionospheric disturbances (TIDs) over Kharkiv with periods of 40–80 min occurring in the time range between 09:00 and 10:30 UT on November 22 and between 10:00 and 12:00 UT on November 23, 2012 during and after the operation of the EISCAT heater facility. The duration of these disturbances were less than 120–180 min. The relative amplitudes of the TIDs in electron density ranged from 0.05 to 0.15 and those in electron and ion temperatures were about 0.02 – 0.05. Assuming that these TIDs have been generated in the heated region, we described the possible mechanisms of their generation.Документ Automatic data collection for incoherent scatter complex(НТУ "ХПІ", 2014) Kozlov, S. S.The creation of the automated data collection system for incoherent scatter complex is justified. The main part of the parameters influencing the control action was considered. The simplified implementation of automated data collection system is presented.Документ Simultaneous determine of Doppler shift and group delay time using amplitude modulated chirp-signal(НТУ "ХПІ", 2014) Kolchev, A. A.; Nedopekin, A. E.; Shumaev, V. V.New method of the simultaneous measurement of the frequency dependencies of Doppler shift and group delay time of separate ionosphere modes by means of amplitude modulated chirp signal is presented in this paper. The algorithms of data processing are presented.Документ Simulation of ionospheric plasma velocity along the geomagnetic field lines due to the horizontal neutral winds(НТУ "ХПІ", 2014) Grinchenko, S. V.; Dziubanov, D. A.; Ziuzgina, Iu. E.With use of horizontal neutral winds model HWM93 there are calculated the elements of a global picture of thermosphere circulation, the changes of value and direction of thermosphere wind over Kharkiv. The calculations of constituent part of vertical component of ionospheric plasma velocity caused by horizontal neutral winds were made.Документ Seasonal anomaly in variations of global distributions of F2-layer electron density according to CCIR model(НТУ "ХПІ", 2014) Grinchenko, S. V.There are presented the global distributions of electron density ne maxF2 and height hmaxF2 of the main maximum of ionosphere. There are analyzed the basic regularities of longitude-latitudinal variations of these parameters in the northern and southern hemispheres. The main attention is given to the effect of seasonal anomaly. It is shown that, according to calculations by the CCIR model seasonal anomaly appears at latitudes between 15 and 60 degrees N. approximately from 9 to 12 hours of local time. In the southern hemisphere the seasonal anomaly is not observed.Документ Variations of the electric field zonal component, the vertical component of the plasma drift and neutral wind velocities in ionosphere over Kharkov (Ukraine) during August 5–6, 2011 and November 13–15, 2012 magnetic storms(НТУ "ХПІ", 2014) Domnin, I. F.; La Hoz, C.; Lyashenko, M. V.The modeling results of the zonal electric field and the vertical component of the plasma transfer velocity due to electromagnetic drift during August 5–6, 2011 and November 13 – 15, 2012 magnetic storms were presented. Confirmed that has a penetration of electric fields from magnetospheric origin in the mid-latitude ionosphere during strong geomagnetic disturbances. For the considered disturbed periods the neutral wind parameters were calculated using Kharkov incoherent scatter radar data.
