对东方红一号卫星短波信号监听结果的分析

1970年4月24日至5月3日在海南、湘西和关中三站对我国第一颗人造卫星东方红一号的20MHz无线电信号进行了监听。本文对监听记录进行了分析,并且对超视距传播机制进行了探讨,提出了由波导、耳语廊和滑行传播方式组合成的四种可能的短波超视距传播模式,以解释此次监听实验取得的结果。

ANALYSIS ON THE MONITORING RESULTS OF THE SHORT WAVE SIGNALS FROM THE SATELLITE DONG-FANG-HONG I

From April 24 to May 3, 1970, the 20 MHz radio wave signals from the first Chinese artificial satellite Dong-Fang-Hong I were monitored at Station Hainan, Xiang-xi and Guanzhong. In this paper the monitoring records are analysed, the mechanism of the beyond-the-horizon propagation is discussed, and four possible models for the short wave beyond-the- horizon propagation composed of the wave guide, whispering gallery and sliding propagation mode are proposed, by which the results obtained from this monitoring experiment may be interpreted.
