UHF Propagation Effects in Scintillated Environments

Abstract

Calculational methods for examining the effects of striations on UHF signals are presented. The advantages of each method are discussed. Calculations are presented which illustrate the various expected effects on signals from different striation structures. The calculations demonstrate that for ambient environments Rayleigh signal statistics are a reasonable worst case representation. It is also shown that for most cases of interest the ionospheric fluctuation power spectral density or its equivalent is necessary and sufficient to calculate the required signal effects.
