Abstract: A multisensor decision fusion method was created based on theory of factor spaces. According to the decision character of multisensor detection and control networks system, the method of establishing multisensor fuzzy decision metric was put up, and the method of multitarget identification was set up on the basis of the concept of feedback extension. The detection false below 10% can be obtained through the computer simulation. A new approach for multisensor multitarget decision fusion has been provided.
