Algorithm Studying Of Radar And AIS Information Fusion In VTS

VTS plays an important role in protecting sailing, promoting shipping efficiency and protecting environment,etc. By tens of years' construction and studying, VTS in our country has been promoted essentially. The rapid growth of economic and shipping brings forward higher requirement to VTS. At the same time, there are many problems in VTS, such as low system precision, low stability, low net opening and multi-sensor fusion, etc.The application of new technologies has prompted the development of VTS Especially the import of AIS will promote the ability of service and monitor of VTS essentially, but meanwhile the information from radar and AIS is redundancy and correlative. It is an urgent task to effectively fuse the information to improve the intelligence degree of VTS. As a multi-disciplinary technology, the fusion technology of information has developed rapidly in near decades and used widely in the military and civil field. A lot of domestic and international scholars, including operators in VTS, are carrying on the research of relevant subjects in a lot of fields and have brought out a great quantity of research results.Referring to home and abroad research results on information fusion, combing the features of VTS information, the paper studies the radar and the AIS information fusion algorithm, carries on the discussion on the radar and the AIS information fusion algorithm. It has certain theory value and practical application significance. The following results have been yielded:1. The characteristics of the radar and the AIS information have been analyzed2. The characteristics of information fusion in VTS have been analyzed.3. A simple and feasible way to time calibration has been brought forward on the radar and the AIS information4. The MK-NN algorithm has been applied to correlate tracks on the radar and on the AIS information.5. The distributed structure has been applied to fuse the radar and the AIS information...
