Definitions for "Scintillation"
A spark or flash emitted in scintillating.
Signal variation due to naturally-ocurring (or sometimes man-made) irregularities in the ionopshere. The effect is the same as the visible twinkling of stars due to variations in the atmosphere. Scintillation is readily identified in the data. Scintillation is most easily explained by analogy to a diffraction grating. Ionospheric irregularities are the equivalent of the diffraction grating. The received signal is then the sum of signal from multiple paths. As the path lengths change the signal varies due to constructive and destructive interference, hence the star twinkles. In other words, scintillation is variations in amplitude, phase, polarization and angle of arrival of a radio wave upon passing through the ionosphere, such as would occur with a satellite signal. Scintillations can be severe (especially near the equator) and present problems to communication services.
Mirror-like reflections from the facets of a gemstone as it turns in the light.
Signal fading due to atmospheric effects that focuses and defocuses the radio waves. Can last for tens of seconds or occasionally minutes. Highly variable with time of year and elevation angle of the earth station.
Regarding electromagnetic wave propagation, this is a random deviation (usually small) of the received field strength about its average value.
A random fluctuation of the received field strength caused by irregular changes in the transmission path over time.
