Analysis of Electron Density-Profiles in the Lower Ionosphere.
Abstract
This report addresses two separate aspects of the effects of the lower ionosphere on ELF/VLF/LF propagation. First, full-wave calculations are performed to assess the effect of a ledge of ionization in the 55-km to 65-km altitude range (e.g., C-layer) on long-path propagation. Second, relationships among wave frequency, incidence angle, and refraction heights are derived. (Author)
