舰船无线通信中数据链测试技术的研究

Application of data chains test techniques in ship-borne wireless communication

当前,船舶的无线通信发展对数据链系统提出新要求。无线通信网络可以分为信源、发送设备和接收设备,在所有模块中最核心的是信号频率合成系统。针对数据链系统中的网络拓扑结构,本文实现了基于定向天线的定向通信技术,并设计了跳频同步技术。依据数据链系统的协议栈模型,本文设计针对系统延时、编码保密度和稳定性的数据链测试技术。

At present, the development of ship-borne wireless communication has raised new requirements on data chain system. The wireless communication system can be divided into message source, transmitting device and receiving device, in which the core part is data chain system. Targeting at net topology structure of data chain system, this paper implements directional communication, and designs the hopping frequency techniques. Based on protocol stack model in data chain system, this paper designs testing techniques on system latency, encoding encryption and stability.
