摘要
本文根据我国铁路的地形特点及列车无线的通信方式要求,对于VHF/UHF电波沿铁路的有关特性进行了试验和研究,给出了许多经验公式、曲线、图表及有关参数因子;对电波传播的一些模式进行了讨论和验证。所得出的结果和结论是通过2万多公里实测而得出的,基本可满足工程设计等方面的需要,同时为进一步升展铁路列车无线中的场强预测和计算机辅助设计打下了基础。
In the paper, the characterastics of radio wave propagation along rail lines in China were described. According to the topography classifications, many experiment formulas, charts and curves have been abtained through extensive field surveys and measurements. In addition, the practicability about some wave propagation models has been appraised and vertified. Some results given in this paper can be utilized in fieldstrength predictions and line designs of the train radio systems.
