Data Fusion In Database Technology

A database system is needed to support the fusion algorithm better for more and more data to be treated in multisensor data fusion system. This thesis is concerned with database technic in data fusion, exploiting a database system to support data fusion algorithm primely. It includes several parts as follows:1. Briefing the data fusion and its processing technic, including the conception, radical theory, function model, and the facing problems.2. The fundamental program to multisensor data fusion is track correlation and track fusion. Study a multifactor fuzzy synthesis track correlation algorithm, a two hierarchical filter algorithm and the present statistical model in this paper. The simulation results show that multitarget tracking can be successfully finished by this kind method.3. Introducing the database technic and its development. Emphasizing on Relation Database technic and briefing some new database technic.4. Database technic in multisensor data fusion is the application of the database technic in data fusion. According to the demand of data fusion for the data, establish a real-time database by using the Object-Oriented technology to fulfill the real-time demand of fusion algorithm. And establish a history database by Relation Database. The data in data fusion system can be managed through this two database. In this way the data fusion system can work efficiently.
