- Abstract
In this paper, we study the amplitude and phase characteristics of VLF signals of an anthropogenic origin during solar proton events using the methods of a computational experiment. We consider the events of October 30, 2003 and January 23, 2012. Electron density profiles are plotted using data from the VHF EISCAT incoherent scatter radar located in Tromsø, Norway. Based on the processed data of computational experiments, that under the conditions of solar proton events, mainly amplitude distortions of VLF signals were shown to be observed while there is a frequency dependence of the magnitude of distortions of the signals of the RSDN-20 long-range navigation radio system. The signal phases of the RSDN-20 system are less affected by weak solar proton events. The effect of the lower boundary of the Earth-ionosphere waveguide in the cases of propagation of signals from the RSDN-20 system over the surface of land and ocean during a solar proton event was studied.
