Amplitude scintillations occuring simultaneously with rain attenuation on satellite links in the 11-GHZ band
Abstract
It is shown that fast amplitude fluctuations in the received signal on earth-satellite links can be mathematically separated from slow amplitude variations caused by rain attenuation. Amplitude scintillations are described in terms of their power spectra and the distribution of standard deviations and amplitudes. The cause of amplitude scintillations occurring simultaneously with rain attenuation is explained based on a comparison among scintillation measurements carried out during rain events, clear weather scintillations, and calculations of scintillations induced by scattering from raindrops.
