Features of application of the extremely-low-frequency–very-low-frequency atmospherics spectrum analyzer for monitoring the earth–ionosphere waveguide state

Аннотация

Features of the operation algorithm of the atmospherics spectrum analyzer and its application for diagnosing the earth–ionosphere waveguide are discussed. It is shown that the selected structure of the spectrum analyzer is expedient. The results are based on the seasonal data obtained at two Polar Geophysical Institute (PGI) observatories, which are located at polar latitudes (“Lovozero” in the Murmansk oblast and “Barentzburg” at the Spitsbergen archipelago).
