摘要
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。
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,Xiangxi 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.
