【摘要】 船舶交通管理系统(Vessel Traffic Services)在保障船舶航行安全，提高航运效率和保护水域环境方面发挥了重要的作用。我国VTS经过几十年的建设和研究，获得了本质上的提高。经济和航运事业的迅速发展，对VTS提出了更高的要求。VTS在发挥重要作用的同时，也存在着系统精度低，稳定性差，网络开放性差和多传感器信息融合等问题。 新的技术手段在VTS中的应用，推动了VTS的迅速发展，特别是船舶自动识别系统(Automatic Identification System)的引入，将从根本上提高VTS的服务和监控能力；同时，雷达、AIS等各种传感器提供的信息存在着冗余相关，如何将这些信息进行有效的融合，提高VTS的智能程度，是亟待解决的问题。信息融合技术是近几十年迅速发展并在军事和民事领域得到广泛应用的、多学科交叉的技术。国内外很多学者在多个领域进行着相关课题的研究，VTS工作者也在自己的领域进行着探索研究，并取得了一大批研究成果。 本文针对VTS中雷达和AIS信息的融合算法进行了探索研究，借鉴国内外信息融合方面的研究成果，结合VTS信息的特点，对雷达和AIS信息融合算法进行了探讨，具有一定的理论价值和实际应用意义，并取得了以下成果： 1．分析了雷达和AIS信息的特点： 2．分析了VTS中信息融合算法的特点； 3．提出了简便可行的雷达和AIS信息的时间校准算法； 4．采用修正的K近邻域法(MK-NN)对雷达和AIS信息进行航迹相关判断； 5．采用分布式结构对雷达和AIS信息进行融合； 6．利用Matlab对雷达和AIS信息的航迹相关判断进行仿真和模拟。更多还原

【Abstract】 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更多还原
