Abstract

We present the results of experimental verification of the spectral-polarization method which we proposed earlier to measure the interference pattern velocity by analysis of three mutually orthogonal projections of the radio-signal field vector using a single receiving antenna. Measurements were performed for an HF radio path about 100 km in length, with the simultaneous monitoring of the ionospheric situation by an oblique-incidence sounding chirp ionosonde. We used nighttime periods in which we observed a stable one-mode reflected radio signal to eliminate multipath effects in the analysis. The mean values of azimuthal and zenith angles obtained by this method differ by no more than 2°–5° from the calculated values. The mean velocity of traveling ionospheric disturbances (of the order of 50 m/sec) and their propagation directions (north-western, changing to northern in the morning hours) for these periods of time are consistent with the existing data.
