一种用于增强轨道交通安全性的窄波束天线

内容简介：针对国内轨道交通系统安全事件频发的问题，提出在车-地链路之间采用窄波束扫描天线代替之前广泛采用的宽波束天线，通过借助其定向波束方向性强、主波束方向及副瓣控制便捷等优点，克服现有CBTC系统存在的列车控制信号与车载AP信号相互干扰的问题，保障城市轨道交通系统的正常运行。

Abstract：This paper proposes the narrow-beam scanning antenna instead of the previous wide-beam antenna applied in the vehicle-ground link of rail transport system to deal with the frequent accidents of domesticrail transport system. The existing conflict problems between ATC and vehicle-carrying AP in CBTC system can be solved via strong directivity of narrow-beam scanning antenna and easy control of the main-beam antenna's direction and side lobe,thus guaranteeing the normal operation of urban railway transport system.
