Application of two-dimensional TEC perturbation maps during the modified ionosphere by SURA powerful radio wave emitting

The first results of TEC perturbation mapping to investigate the artificial plasma perturbations caused by powerful HF radiowave emitting of the ionosphere are presented. We analyze the results of measurements made by SURA in the daytime between 14:45 and 17:30 UT on October 1, 2016 with a 15-minute emitting interval and 15-minute pause interval. To observe the ionosphere modification the dense GPS/GLONASS receiver's network was used. It was found that heating of the ionospheric plasma by powerful radio waves is able to effect on characteristics of natural TIDs, e.g. increasing their amplitude and wavelength.
