摘要
电波传播的规律性对工作在不同频段的无线电通信系统以及各种用途的无线电测试系统的计算和设计,都有十分重要的意义。针对中国北部丘陵地区的电波传播特性设计了测试方案,依据测试方案对该地区超短波频段的电波传输损耗进行了准确的测试,同时与加金属网屏蔽效果进行了测试和对应比较,最后对测试结果进行了分析。结果表明此实验测试数据对从事超短波通信总体研究和实际设计的人员均有重要的参考价值。
The regularity of electric wave propagation is very valuable to the computation and design of the wireless communication system operating at various frequency bands and various wireless testing systems. In this paper, a test scheme is developed for testing the electric wave propagating characteristics in upland areas. Based on the above method, a precision test is completed in a upland region of North China, and also the effect of wire netting shield is investigated. The comparison and analysis indicate that the method given in this paper is very useful to people who are engaged in the UHF-band communication research and the design work.
