摘要
AIS系统是现代船舶安全航行不可或缺的一项技术应用,主要由岸基(基站)设备及船载终端设备组成。而VHF天线作为AIS基站最重要的组成部分之一,天线的性能、配置、安装规范等相关设置直接影响着AIS系统的接收性能,从而影响船舶的安全航行。为尽可能地提高AIS系统的接收性能,本文紧抓天线架设高度这一重要影响因素,通过理论计算与实地测试相结合的方法,首次在开阔海域环境下确定了AIS基站VHF天线的最佳架设范围,为相似条件下VHF天线高度的架设提供了重要参考。经实测结果表明,在开阔海域环境下,VHF天线的最佳架设高度范围为50至60米之间。
The AIS(Automatic Identification System)is an indispensable technological application for modern maritime navigation safety,primarily composed of shore-based(base station)equipment and shipborne terminal devices.As one of the most critical components in AIS base stations,the VHF antenna’s performance,configuration,and installation specifications directly impact the reception capabilities of the AIS system,thereby influencing vessel navigation safety.To optimize AIS reception performance,this study focuses on the crucial factor of antenna installation height,through a methodology combining theoretical calculations with field testing,we have for the first time determined the optimal installation height range for VHF antennas at AIS base stations in open sea environments,providing critical references for similar deployment conditions.Field test results demonstrate that the optimal installation height for VHF antennas in open sea environments falls within the range of 50 to 60 meters.
