Track fusion in networked antiaircraft fire-control system

网络化防空火控系统是网络化作战形式不断发展的产物.本文以网络化防空作战为背景,针对网络化防空火控系统的体系结构及航迹融合问题进行了研究.将网络化控制系统的方法引入防空火控系统的研究中,提出了一种网络化防空火控系统的体系结构.为了保证系统在该体系结构下更好地工作,对航迹融合方法进行了研究.提出并构建了基于联邦Kalman滤波技术的航迹融合方法,其滤波结构适应于灵活开放的体系结构,同时子滤波器可以根据网络传输状态,处理数据丢包和时延的情况.试验结果表明,融合后的数据精度得到了提高.该方法为网络化防空火控系统的设计与实现奠定了良好的基础.

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.
