| 摘 要： | 本文研究了我国中纬台站西安观测到的日本同步卫星ETS-2 136 MHz讯号的幅度和相位闪烁特性。发现幅度谱和相位谱的高频特性可用弱闪烁理论来解释。在低频端,幅度谱和相位谱经过一个平坦的频域后开始下降,这与弱闪烁理论矛盾。文本将解释这些矛盾。似乎此处的结论更为合理些。

| Abstract: | 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. |
