There is an urgent problem of forecasting and taking into account these distortions in the characteristics of radio waves during the operation of the mentioned radio equipment. Purpose of the research is theoretical and experimental studies of the influence of high-energy processes of artificial and natural origin on the ionospheric channels of telecommunications, radar, radio reconnaissance and navigation, determination of the magnitude of distortions of the main radio signal parameters, as well as the development of recommendations for taking into account these effects in the operation of radio engineering systems. popup.nrat_date 2024-12-09 Close
