Dudnik O. Dynamics of radiation belts and noise radio emission in the near Earth space as an indicator of the solar activity manifestation.

The thesis refers to research of sporadic radio emission of the near Earth space, investigation of high energy charge particle fluxes in the Earth's plasmasphere. The experimental methods of high frequency sporadic radio bursts ground registration, and of satellite monitoring of high energy charge particles are developed in the work. The methods of complex analysis of satellite information and ground-base data are developed too. It is shown for the first time that generation of sporadic radio bursts is connected with the acceleration, radial and pitch-angle drifts of electrons inhabiting radiation belts of the Earth. Estimations of synchrotronous emission power by electrons in the dipolar magnetic field of the Earth are conformed with the observing data, that predict the exponent of power function of electron's distribution on the energy and on the pitch-angles. For the first time it is revealed the high energy electron fluxes on the altitude of 550 km outside Van Allen radiation belts; it was detected too variable electron fluxes under radiation belts on the middle latitudes as a response on substorms with Dst < -30 nT. It is defined empiric lifetimes of electrons in the belts in 2 energy ranges. It is proved an anisotropic character of the electron's motion under radiation belts while in the South Atlantic Anomaly the fluxes have isotropic character. The particle energy spectra inside the Anomaly region are enriched with high energy electrons more than the spectra at radiation belt's spurs. For the first time it is revealed additional inner electron radiation belt of the Earth at L ~ 1.6 located below the Van Allen inner radiation belt beyond the Brazil magnetic anomaly zone.
