英文摘要：

The performance indicators of information fusion system and network dynamics parameter are combined in order to analyze the scale - free characteristics of information fusion system. As a result, the scale - free BA model is used to be the topology model of information fusion system. According to the special requirements of information fusion system, the corresponding improvements to the growth and preferential attachment arithmetic are made based on the BA model. An advocated model is given to be the improved BA model of information fusion system. The average length is deceased by 10% in the improved model, and clustering grows larger. The improved BA model is more suitable considering the dynamic characteristics of information fusion system.
