Description

 Object of study is the plasma environment of the Earth and Jupiter. Aim of the work is the processing and analysis of data of broadband spectral structures of sporadic decameter electromagnetic radiation of Jupiter using observation databases obtained on unique radio telescopes of IRA NAS of Ukraine. Processing and analysis of retrospective databases of observations of the spatial-spectral behavior of the effects of HF signal scattering on the AIT. Results and scientific novelty – At this annual stage of research, the spectral features of artificial radio emissions of the Earth's ionosphere under the influence of controlled radiation of a powerful ground stand at a pump wave frequency close to the frequency of electron gyrogaromonics are considered. The first time, a new effect of the spectrum splitting of stimulated radiation at the initial stage of heating is found. The spectral features of stimulated electromagnetic emission under the double plasma resonance (DPR) conditions are studied. Based on the DPR effect at the ion cyclotron harmonics, a model of the quasi-harmonic emission bands origin («zebra» structure) in the Jovian sporadic decameter radiation spectra is developed. Within the frame of the VIP4 magnetic field model the active longitudes of the Io satellite magnetic tube, on which radiation sources with «zebra» structure can be located, are determined. The plasma density, its height distribution in the source, as well as the energies of emitting ions and scattering electrons are estimated. Methods and equipment are modern information and telecommunication technologies, mathematical theory of processes in space plasma, remote sensing of space plasma, polar LFW observatories, decameter range radio telescope UTR-2, highly efficient digital recording receivers.
