D-S theory based on entropy and its application in sensor fusion

The reliability of the evidence and its weights are analyzed from itself and relation between evidences.Therefore,information entropy of evidence is introduced;the method of computing reliability is also presented.In order to achieve the reliability of evidence from the relation between evidence,fuzzy relation matrix is introduced,and the fuzzy relation matrix is used to show importance of evi- dence.Experiment results show the effectiveness and robustness of this method.
