摘要
AIS基站天线通信距离及覆盖区域难以根据交通密度进行调控等问题一直困扰着各沿海船舶交管中心(VTS)。针对上述问题,设计了AIS基站可控式二元八木天线阵列,并对该天线进行大量实验和仿真。通过实验发现,天线阵在天气良好条件下的最大通信距离可达50海里以上。且天线覆盖区域可以快速变换,进而监控区域可以动态调整。该天线阵既可以作为AIS基站天线,也可以作为卫星基站天线。
The communication distance and coverage area of the antenna of the AIS basic station is difficult to adjust and control according to traffic density.This question has been troubling the Coastal Ship Traffic Control Center(VTS).To solve the question above,AIS binary yagi antenna array has been designed,and a lot of simulations and experiments have been done.It turns out that the maximum communication distance of the antenna array in good weather is more than50nautical miles.And the coverage area of the antenna can change rapidly,so that the monitoring areas can be dynamically adjusted.The antenna array not only can be the AIS basic station antenna,but also can be the satellite base station antenna.
