Mylovanov Y. Physical Processes in the Atmosphere-Ionosphere Radio Channel Caused by the Action of High-Energy Sources

The dissertation is devoted to the solution of the actual problem associated with the study of the impact of high-powered radio emission and high powered space forces on atmospheric-ionospheric radio channels. The work substantiates the problems that allowed to achieve the stated goal of the study: the mathematical modeling of a number of physical processes in the atmosphere-ionospheric radio channel caused by the impact on the environment of the flight and the explosion of the Chelyabinsk meteoroid and the powerful radio emission of the terrestrial radio system of the medium, high and ultrahigh frequency ranges. Results obtained: 1. For the first time was modeled in detail the amplitude of self-influenced high powered radio waves, for day and night conditions. The frequency dependence of the self-influence multiplier and relative perturbations of temperature and electron concentration was analyzed. The conditions for the creation of artificial plasma formations at altitudes from 30 to 80 km have been investigated separately. 2. Using the equations of meteoric physics and using numerical methods, the inverse problem was solved for the first time as the finding of altitude and temporal dependencies of the basic parameters of the unique Chelyabinsk meteoroid from observations of trajectory data. Calculated high-temporal dependence of mass, mide area, intensity of radiation, temperature of surface of radiation, estimated coefficients of dynamic resistance and ablation, as well as specific energy of ablation. 3. Using GPS satellites, the basic parameters of the wave disturbances generated by the flight and explosion of the Chelyabinsk meteoroid for the first time were determined.
