摘要
本文主要对甚高频通信中的电磁干扰进行分析研究,首先对无线电频段划分进行介绍,清晰了解无线电频段对于分析电磁干扰有重要的意义,然后对甚高频通信以及电磁干扰进行分析研究,最后分析了天线的合理设置对于降低甚高频通信干扰的作用,并推导发射天线与接收天线间的隔离度。
This paper mainly analyzes the electromagnetic interference in VHF communication. Firstly, it introduces the radio frequency band division. It is important to understand the radio frequency band importantly for analyzing electromagnetic interference. Then, the VHF communication and electromagnetic interference are analyzed and researched. Finally, The effect of the reasonable setting of the antenna on reducing the interference of the VHF communication is analyzed, and the isolation between the transmitting antenna and the receiving antenna is derived.
