在短波通信系统设计和应用中,人们需要充分考虑短波信道传播特性、信道路径损耗和电离层结构特征等信息,但目前这方面信息十分有限,且多数为理论依据或早期的粗劣数据。在国产测高仪的基础上设计了一种短波信道探测系统,该系统能够实时地、精确地获得短波通信链路上信道链路损耗和频率特性曲线,这对短波通信应用和系统设计有重要的辅助意义,试验结果也证实了这一结论。
在短波通信繫統設計和應用中,人們需要充分攷慮短波信道傳播特性、信道路徑損耗和電離層結構特徵等信息,但目前這方麵信息十分有限,且多數為理論依據或早期的粗劣數據。在國產測高儀的基礎上設計瞭一種短波信道探測繫統,該繫統能夠實時地、精確地穫得短波通信鏈路上信道鏈路損耗和頻率特性麯線,這對短波通信應用和繫統設計有重要的輔助意義,試驗結果也證實瞭這一結論。

In the design and application of the shortwave communication system,the characteristic of shortwave channel propagation,channel loss,characteristic of ionosphere structure should be adequately considered. But the information in this aspect is too old or not exact,and most of them are only theoretical foundation. A system of short wave channel detection based on height indicator made in China was designed,which can measure the channel link loss and frequency characteristic of the shortwave communications link timely and accurately. It has important auxiliary significance for the design and application of shortwave communication system,and the experiment results verify this conclusion.
