Abstract

It is shown that during diffusivity of ionosphere its bandwidth of coherence may shrink to hundreds of hertz. Frequency-selective fading appears in these cases and the noise error when measuring ionospheric virtual height increases by 1–2 orders if compared to the normal ionospheric conditions.
