Abstract: In this paper,a new structure of distributed multi-sensor intelligent attribute fusion system is given. By use of fuzzy neural network ,the environmental-and-expert verbal information is introduced into the fusion system and a new intelligent attribute information fusion algorithm is presented. An example of automatic target recognition fis given by use of the information from IFFN ,IRST and RADAR.The simulation shows that the new algorithm can speed calculation greatly,and the system has better ability of resisting the environmental disturbance and higher system reliabilily.
