海上平台通信中的天线组阵方式分析

Analysis to antenna array mode in ship communication

为提高信息传输中的稳定性与可靠性,提出了将自适应天线阵列应用于海上平台通信的方案,并对均匀直线阵和均匀圆环阵的阵列结构、波束宽度、分辨力、测向范围等性能进行了对比分析,得出结论:均匀直线阵只能实现180°范围扫描,但是在一定范围内具有较高的分辨力;均匀圆环阵分辨力较低,但是可实现全平面扫描、尺寸较小、波束形状及分辨力不随波束指向改变。在海上平台通信的实际应用中,应根据实际需求并结合不同组阵方式的优缺点进行选择使用。

For increasing stability and reliability in radio communication,a scheme of applying adaptive antenna array in ship communication is given in this paper.Based on analysis of array structure,beam width and resolution,we can make the conclusion that a uniform linear array can scan only from-90° to＋90° but has higher resolution in a certain range,a uniform circle array has lower resolution but can scan from-180° to＋180° with smaller dimension and its beam form and resolution will not change in different beam pointing.When applied in ship communication,we should select different antenna array mode based on their characteristics and actual requirement.
