Abstract
The article is dedicated to study of the atmospheric noise properties in the range of intermediate and decameter waves in the Western Bering Sea zone, where such observations were not carried out earlier. Since it is impossible to use the radio equipment of ships for such measurements, we used devices using the technology of software-defined radio systems. The measurements were carried out along the coast of Kamchatka and made it possible to establish the characteristic temporal, spatial and frequency variations in the parameters of atmospheric noise. It was found that the radio noise intensity distributions proposed due the recommendations of the International Telecommunication Union differ significantly from the real ones. The obtained data analysis showed the possibility of realizing a decameter range of circumpolar latitudes, unfavorable for radio engineering systems – a sharp increase in the intensity of radio noise due to the coincidence in time of several thunderstorm activity foci and a simultaneous decrease in absorption in the ionosphere.
