Study on the Differences of the Dynamic Target Information of the Marine Radar and AIS

Both radar and AIS (automatic identification system) are the most important navigational equipment for a ship. But, there are some differences between them in the performance and the target information. The paper studied the difference and characteristic of the dynamic target information from the radar and the AIS. Based on the survey platform of the target information system developed by the own, measurements were vastly done for the target's dynamic information, including position, speed and course. It evaluated the differences between them, and got the very important statistic results. It offers not only the valuable references for the voyager to understand and identify the target information characteristic, but also the research foundation of the information processing such as target information fusion, and the intelligent ship collision avoidance and so on.
