A New Method for Marine Surveillance Based on AIS Message Detection

A new method based on automatie identification system （AIS） message detection with information fusion for marine surveillance is presented. Firstly multiple MS receiver sites, which are located on various platforms throughout the coastal bases, vessels, oil platforms, buoys and other ocean observing stations, can get ship identity, position, course, speed and other voyage information. Then according to AIS message sources, there are two levels of multi-sensor data fusion including the theory of data-level and feature-level fusion. Finally the targets can be determined according to AIS message as well as multi-source information fusion with radar and video monitoring data. Therefore the AIS technology can be used for both environmental monitoring and the security of the nation.
