要約

Observational results are presented concerning time variations in the amplitudes and Doppler frequency shifts of HF radio waves propagating along four oblique paths during a partial (magnitude about 0.8) solar eclipse occurred over Central Europe. The eclipse was found to produce essential broadening of the Doppler spectra and alternating variations in the Doppler frequency shifts. The measured results are in good agreement with theoretical estimates of the solar eclipse effects.
