A Study of Artificial Modification of the VLF Propagation Characteristics of the Plasmasphere.
Abstract
This report describes theoretical studies related to man-made disturbances of the upper atmosphere which can affect VLF wave propagation. The purpose of our research was to estimate the effect that artificially created plasma holes could have on whistler made signals propagating through the ionosphere. In the course of our research, we have developed models which describe the flow of reactive vapor which can be injected into the plasma layers. Our research has considered the influence of the modified ionosphere on propagation of HF and VHF as well as VLF radiowaves. During the final period of research, we have found evidence of man-made perturbation of the earth-ionosphere waveguide.
