本文提出了一种利用现有电视广播电波测量UHF频段电波传播的独创性方法，并描述了如何在室外移动环境中开发一种UHF频段电波传播的移动式测量系统。给出了测量系统的测量极限、频率选择性、天线方向性和温度特性。作为UHF频段无线电传播实验的结果，本文给出了广岛市的接收水平等值线图。这张地图阐明了接收到的电平取决于周围的地物。
This paper proposes an original method for UHF band radio propagation measurements by use of existing TV broadcasting waves and describes how to develop a mobile measurement system for UHF band radio propagation in mobile outdoor environments. And the paper shows measurement limitation, frequency selectivity, antenna directivity and temperature characteristics of our developed measurement system. As a result of experiments in UHF band radio propagation, the paper shows the received level contour map of Hiroshima City. This map clarifies that the received level is dependent on the surrounding features.
