A Study of the Scintillation for the Geostationary Satellite Signal

In this paper the features of the amplitude and phase scintillations of 136 MHz signal transmited from the Japeness geostationary satellite ETS-2 and received at a mid-latitude station, Xian, were studied. They show that the high frequency features of the amplitude and phase spectra can exactly be explained by the weak scintillation theory, but at low frequency end the spectra go through a flat frequency region at first and then start to drop. These contradict the results obtained from the weak scintillation theory. These contradictions are explained in the paper. It seems that the conclusions obtained here are more reasonable.
