Ionospheric scintillation is a rapid fluctuation of radio-frequency signal phase and/or amplitude, which is generated as a signal passes through the ionosphere. Scintillation occurs when a radio frequency signal, in the form of a plane wave, traverses a region of small scale irregularities in electron density. The irregularities cause small-scale fluctuations in refractive index and subsequent differential diffraction (scattering) of the plane wave, producing phase variations along the phase front of the signal. As the signal propagation continues, after passing through the region of irregularities, phase and amplitude scintillation develops through interference of multiple scattered signals. The first Ionospheric Scintillation Monitor in Vanimo was installed in 20/08/1999.
