摘要
在NLOS环境下分析了超宽带(UWB)信号及信道传输特性,针对信号的传播特性给出了UWB信号应用于船舶避碰的工作原理,确定合适的接收设备以实现信号的可靠接收,从而对两船之间的距离及方向进行实时监测,使工作人员根据判断结果采取一定的避碰措施,保证船舶航行安全。
In this paper, ultra wide band （UWB） signals and the channel transmission characteristics are analyzed in NLOS environment. The work principle of UWB signal application in ship collision avoidance is proposed on the spreading characteristics of signal, determining suitable equipments to receive signals. The system can real-time monitor the distance and the direction of the two ship in order to taking collision avoidance measures according to judgment results by staff which guarantees navigation security of the ship.
