More papers and researches are focused on distributed multi2sensor fusion ,which is decision2level fusion. A new fuzzy decision fusion method with fuzzy attribution for target recognition application is described. The fuzzy decision function modifies parameters with auto2adapted algorithm to get better classification probabaility. Computer experiment is done by the fuzzy decision fusion system ,and the results are analyzed. It is shown that the method can adapt to different fusion applica2 tion ,and achieve better recognition result.
