英文摘要：

Asynchronous trackfusion of multiple networknodes is one of the key techniques in handling the networked targeting combat manners. Making the best use of asynchronous trackinformation from multiple nodes, we improve the precision of networked targeting. First, the major techniques for asynchronous fusion in the networked targeting environment are analyzed, from which we propose three different asynchronous fusion policies for networked targeting. Next, the asynchronous trackfusion algorithm and computation steps are developed according to the optimal estimation theory. Finally, the simulation experiments are performed, which validate the efficacy of the proposed methods in asynchronous trackfusion. The effect on fusionperformances from the fusion period is also analyzed.
