Ionospheric wave
Web23 mrt. 2024 · Ionospheric observations provide an effective and unique means of detecting these waves and some other oscillations, occurring in the entire atmosphere. WebThe ionosphere is dispersive, which means that the apparent time delay contributed by the ionosphere depends on the frequency of the signal. During the signal’s trip through the ionosphere, this dispersive property …
