Abstract

The author presents a technique for investigating the influence of layered fluctuations of the refractivity on transhorizon radio-wave propagation in an evaporation duct. Numerical calculations show that these fluctuations have a significant influence on the transhorizon propagation. It is found that the mean intensity of the EM field considerably exceeds that in the case of an undisturbed waveguide and decreases along the earth´s surface more slowly. The field distribution obeys the logarithmic normal distribution.<>
