摘要
基于ROF技术的高天线系统在通信领域的应用是一种有效且低成本的解决方法,首先介绍了该系统的组成,并通过菲涅尔绕射理论说明了其工作原理,然后分析了高天线系统在通信领域的应用,介绍了目前高天线系统通过小型系留飞行器承载升空及利用光纤拉远拉高的两种典型应用方式,并列举山区升空试验数据来说明高天线系统在不同工作频段对增加通信距离的作用,减少了通信盲区。
The application of high antenna system based on ROF technology is an effective and low-cost solution in the field of communication. In this paper, the system composition is introduced and its principle is illustrated according to Fresnel diffraction theory. The application of high antenna system in the field of communication is analyzed. Specifically, two typical application modes including small tie-down aircraft and fiber based on high antenna system are presented. Finally, test data collected in maintains are listed to demonstrate that high antenna system can increase communication distance and reduce communication blind area according to different band.
