Abstract
The Doppler spectrum of an exact time harmonic radio signal for the frequency of 5 MHz on the Moscow–Akademik Vernadskii Ukrainian Antarctic station radio path in November 2002, which had two clearly defined spectral groups, has been analyzed. It is shown that an insignificant frequency shift corresponds to a standard radio wave propagation in a short direct direction. The assumption that the formation of a spectral group with a considerable frequency shift is refraction is theoretically justified based on a simplified model of the morning terminator transition region. The field strength, signal-to-noise ratio, and Doppler frequency shift obtained in the scope of the IRI-2001 extended global ionospheric model for the classical radio wave propagation modes on a superlong radio path are estimated.
