南极科考站的短波通信系统设计

The Design of Shortwave Communication System in Antarctic Research Station

利用南极地区的电离层结构特性以及中山站、泰山站、昆仑站电离层临界频率的时间分布,对南极地区短波通信链路上的电离层特性进行分析,提出采用国产化短波通信控制系统搭配水平偶极子天线的设计方案,并进行系统通信链路和可通频率等的技术论证,得到南极地区的电离层变化情况及系统的可通信率,从而验证南极地区各考察站之间建设短波通信系统的可行性问题。

Using the structural characteristics of the ionosphere in the Antarctic region and the time distribution of ionospheric critical frequencies at Zhongshan Station,Taishan Station and Kunlun Station,to analyze ionospheric the characteristics on the shortwave communication link in the Antarctic region,and proposed the scheme of using a localized shortwave communication control system with the horizontal dipole antenna,and carried out the technical demonstration of the systematic communication link and the passable frequency,the ionospheric changes in the Antarctic area and communicable rate of the system are obtained.Thus,the feasibility of constructing shortwave communication system between the various research stations in the Antarctic area was verified.
