Abstract
Radar data and automatic identification system(AIS)data have different information advantages,and data fusion can achieve complementary information between the two types of data.Conventional methods require parsing a large amount of AIS data each time when searching for matching data,which heavily relies on computer hardware resources and seriously affects operational efficiency.In response to the problems of difficult matching of large amounts of AIS data and slow cyclic search,this paper utilized the advantages of lightweight databases for convenient data storage and querying and stored a large amount of AIS data parsed at once in the database to avoid duplicate parsing of AIS data and reduce dependence on computer hardware resources.The experiment shows that the method proposed in this paper can reduce the matching time between 30 000 radar data and 100 000 AIS data from 1 225 s and 335 s,achieving efficient search and matching between radar data and AIS data and improving data fusion efficiency.关键词
