Track fusion in networked antiaircraft fire-control system
网络化防空火控系统中的航迹融合

Renovation of networked campaign modality results in the development of networked antiaircraft fire control system. Based on the networked antiaircraft campaign, the architecture of networked antiaircraft fire control system and the method of track fusion are investigated. Theories of networked control system are introduced to the research of the architecture of networked antiaircraft fire control system and the practical construction of such systems. In order to reach better efficiency under the architecture, research on track fusion problems is also studied. Track fusion based on Federated Kalman filter technique is put forward, and the structure of the filter is designed for the flexible and open architecture. Local filter can deal with packet losses and time-delay according to network transmission status. Experiments are performed and the results show that data precision is greatly improved by the fusion. The method could be a strong foundation for the design and implementation of networked antiaircraft fire control system.
