Abstract: Aimed at the recognition problem of multi-targets which have many characteristic indexes，a new fusion method for the fuzzy multi-sensor data is proposed according to Theil disequilibrium index.The method applies Theil disequilibrium index to define the entropy weight，introduces the local decision support degree by the triangular membership function，and utilizes the entropy weight to obtain the global comprehensive support degree.Hence the rule of object recognition is given.The method may avoid the subjectivity of the weight of characteristic indexes，and improve the objectivity and accuracy of target recognition.The applied examples prove that the method is both effective and exercisable.
