Abstract
Recently the significant increase in intensity of researches in the field of the fissile impact on geophysical processes in various environments is noted. Special attention is paid to a research of impact on an ionosphere of a potent short-wave radio emission of heating stands. Today experiments on change of an ionosphere are made generally at stands HAARP, EISCAT in Tromse (Norway). Within the Russian campaign (Tomsk) EISCAT/heating (AARI_HFOX) made from October 19 to October 30, 2016 experiments on impact on an ionosphere F-layer by the radiation potent HF. For assessment of impact of these experiments on geophysical processes mathematical methods carried out the analysis of change of the parameters of the Schumann resonances received on the basis of data from the station of constant observation of the Schumann resonances in the city of Tomsk, the Tomsk State University (Russia).
Highlights
Heating stands unlike traditional methods of diagnostics of an ionosphere give the chance to influence targeted natural ionospheric processes, and, perhaps, to operate these processes
Impact on an ionosphere by powerful Shortwave radiation leads to the fact that the ionosphere (F layer) is heated — in the field of a wave electrons of ionospheric plasma disperse, and disperse nonuniformly, so, the conduction changes and the periodic structure of ionospheric currents is created
Besides the scientific results received in works with heating stands such as discovery of low-frequency radiation of ionospheric current systems (Getmantsev's effect), research of plasma instabilities, optical luminescence of the indignant area, is available a possibility of applied application of these installations
Summary
Heating stands unlike traditional methods of diagnostics of an ionosphere give the chance to influence targeted natural ionospheric processes, and, perhaps, to operate these processes. HAARP on Alaska and "EISCAT" heating stands in Norway technically are the most potent. These stands have the high effective power of radiation, a wide frequency range of "heating", a possibility of radiation in various modes, including the continuous, pulse and amplitude-modulated with a modulation frequency from extremely low-frequency to very low-frequency range, a possibility of scanning of a beam. Schuman's resonance is called the phenomenon of formation of standing electromagnetic waves of low and ultralow frequencies between the Earth's surface and an ionosphere. The Earth and its ionosphere are a huge spherical resonator which cavity is filled with the low conductivity environment. If the electromagnetic wave which arose in this environment after rounding of the globe coincides again with characteristic phase (enters a resonance), it can exist long time
