Abstract

We present a method to diagnose integral parameters of the upper atmosphere thin structure based on the measured fluctuations of trajectory characteristics of the signals from short-wavelength radio beacons operating in the oblique sounding mode. The method is based on the derived functional relations that relate the second statistical moments of the phase and group delay of the signal with the spatial correlation function of fluctuations in the dielectric permittivity of the atmosphere. As a model of the thin structure of the medium, we use the concept of a varying correlation ellipsoid that is self-consistent with the spatial variations of the regular atmosphere. The results of numerical experiments are presented to determine the expected phase fluctuations and the group delay of decameter signals on single-hop tracks by using the calculated integral parameters of the fine structure of the upper atmosphere.
