Application of multi-sensor track fusion technology in fire control radar network

This paper presents a fire control radar networking solution to improve the probability of intercepting the cruise missile. It is the basic idea that fire control radars working alone are linked to the central computer to form a distributed fire control radar network system. Every fire control radar is a node in the network, it can scan and track independent target. At the same time, it sends state information (target state information of node) to central computer. The central computer uses fusion algorithm to produce fused target state information (target state information of system), and then which is returned to node. It has the potential to improve target tracking accuracy and aerial defense domain. Firstly, the functional architecture of the fire control radars network is proposed. Secondly, some robust, practical track fusion algorithms, such as track-to-track association, track fusion and track management etc., are introduced. Finally, track fusion algorithms are tested with different scenario (parallel, cross, bifurcation, maneuvering trajectory). The test result shows that through constructing a fire radar network under low cost, the target track accuracy and the scope of tracking target can be improved largely.
