Abstract

This paper presents the design and implementation of an Automatic Identification System (AIS) receiver with the use of a Software Defined Radio (SDR). AIS devices transmit and receive different navigational data such as location, speed and course of different maritime vessels autonomously and continuously. AIS is used to aid in the safe and secure navigation of different maritime vessels. The concepts of SDR are presented as well as the software required to execute the receiving function. The laboratory setup of the AIS receiver is arranged to acquire raw AIS data from real ships. The raw data is then passed to a set of demodulating signal blocks to acquire the AIS Message. The AIS Message received is decoded and the relevant information is extracted from the AIS packet. To check the result and performance of the SDR-based AIS receiver, the received data is compared to the received signal of a commercial grade AIS transceiver. Based from the results, the SDR-based AIS receiver can effectively and accurately extract AIS messages from the raw AIS data packets.

单通道自动识别系统接收机的软件无线电实现

本文介绍了一种基于软件定义无线电(SDR)的自动识别系统(AIS)接收机的设计与实现。AIS设备可以自主、连续地发送和接收不同海上船舶的位置、航速、航向等不同的导航数据。AIS系统用于帮助各种海上船舶的安全航行。介绍了SDR的概念以及执行接收功能所需的软件。AIS接收机的实验室设置是为了获取真实船舶的原始AIS数据。然后将原始数据传递给一组解调信号块以获取AIS消息。对接收到的AIS报文进行解码，并从AIS报文中提取相关信息。为了检查基于sdr的AIS接收器的结果和性能，将接收到的数据与商用级AIS收发器的接收信号进行比较。结果表明，基于sdr的AIS接收机能够有效、准确地从原始AIS数据包中提取AIS报文。
