The present paper is devoted to the description of an improved method for determination of the ionospheric electron density values by Kharkov Incoherent Scatter Radar. This method allows to improve the resolution of the incoherent signals parameters up to ∼20 km in the range of 100–400 km and ∼100 km in the range of 200–1100 km. This approach was used to investigate variability of the ionospheric...
Different radio sounding techniques are used to the study of the ionosphere state. In the given paper analysis of ionospheric electron density and contribution of different parts of the ionosphere to the total electron content (TEC) was carried out on the base of measurements provided by GPS transionospheric sounding, vertical ionospheric sounding and radio occultation (RO). It was considered the...
In this paper we present the analysis of the ionosphere changes prior to the Japanese earthquake of November 28, 2004 (M7.0). For this purpose we used global TEC maps and measurements provided by GPS-IGS stations and Wakkanai ionosonde which is nearest to the epicenter. Several days prior to earthquake the characteristic anomaly was found out as the day-time significant increase of TEC at the vicinity...
