Fusion of data from AIS and tracking radar for the needs of ECDIS

The paper presents results of the research on problem of radar-AIS data fusion in ECDIS. First the concept of these systems according to IMO is provided, then a set of theoretical information concerning radar tracking and the fusion itself is given and finally numerical research with real data are presented. Two methods of decentralized fusion are examined with the analysis of their parameters. A proposal of calculating covariance matrix for radar and AIS data is given. The research are followed with the conclusions.
