| Popis: | We develop theoretically a method for determining the Doppler frequency shift on individual rays in ionospheric sounding. The method is based on using periodic chirp signals. The potential resolution and range of the measured Doppler-shifted frequencies are determined. Application of this method yields the relationship between the Doppler shift of the propagation-mode frequency and the velocity of a horizontal displacement of the hop tops along the Khabarovsk-Yoshkar-Ola radio path. Significant correlations between the mode order in the ionosphere and the Doppler shift, Doppler-spectrum width, and stationarity time of the propagation channel are found. |
