调频电视场强测量关键问题分析

摘要

云南大理位于云贵高原和横断山脉的结合处，地貌复杂，多丘陵，其复杂的地貌环境对广播电视信号场强的影响较大，且不易于场强的测量。文章介绍了广播电视信号场强电压、电平相关概念，分析了电视广播信号电波特点，并总结了调频电视广播信号电波在空间某点场强的测量方法及注意事项。%In Dali, Yunnan Province is located in the Yunnan Guizhou Plateau and Hengduan Mountains junction, complex landform, hilly, the effect of the complex geomorphic environment of radio and television signal strength larger, and not easy to ifeld measurement. This paper introduced the broadcast television signal ifeld intensity voltage level and related concepts, analyzes the characteristics of the radio and television signal wave, and summarized the FM radio and television radio signals at a certain point in space ifeld measurement method and matters needing attention.
