随着城市规模发展及高楼、桥梁的增多,城市地貌日新月异,这对调频广播覆盖有一定的影响。定期对调频广播覆盖场强进行测量,及时了解覆盖区域及收听效果的变化情况,对广播电台而言意义重大。本文主要针对调频广播信号的特点,对测量场强的方法进行了分析研究,从而提高调频广播覆盖场强测量的准确性和高效性。 With the development of cities and the increase of tall buildings and bridges, the urban landscape is changing with each passing day, which has a certain impact on FM broadcasting coverage. It is of great significance for radio stations to regularly measure the coverage of the FM radio coverage area and keep abreast of changes in coverage areas and listening effects. In this paper, we focus on the characteristics of FM broadcast signals, and analyze the methods of measuring the field strength to improve the accuracy and efficiency of FM field coverage measurement.
