Track Handing Fusion in Data Fusion and Database

Abstract:

Track message is obtained with a lot of adopted sensors. For one sensor, the reliability may not the same in different condition. A reliability judgment matrix for each target is constructed based on the relative reliability of information offered by sensors. Then, the reliabilities of all the sensors for each target and their general reliability can be gotten. A numerical example is presented. The well reliability sensor’s information will be chose to merge with Kalman filter algorithm in tracking handling based on data fusion technique, and gain the best estimate track. According to the demand of data fusion for the data, establish a real-time database by using the objected 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 the two databases. In this way the data fusion system can work efficiently.
