隧道调频广播分布式小天线覆盖研究

Research of Distributed Miniature Antennas' Signal Coverage of FM Radio in Tunnel

本文详细介绍了浙江广电集团在开展隧道调频广播覆盖之前进行的相关测试实验,以隧道调频广播分布式天线覆盖为例,通过实验测试和建模计算,对传统的经验公式进行了修正,在理论上提出了隧道调频广播覆盖传输模型,并通过工程实例,探索隧道调频广播覆盖工程的模式,对调频广播技术的发展有一定的参考价值。

Relevant measurements and experiments,which Zhejiang Radio and TV Group has conducted in developing the FM broadcast signal coverage in the tunnel,are deliberately discussed in this article.By taking the distributed antenna project as an example,the conventional experienced formula is revised according to the modeling and experiment results,and the model for FM broadcast signal coverage in the tunnel is proposed theoretically.With the project considerations,practical parameters of FM broadcast signal coverage in the tunnel are obtained and analyzed.
