Combination Method of Conflicting Evidence based on Mahalanobis Distance

D-S evidence theory is an important method for dealing with uncertainty in high-level data fusion.However,some counterintuitive conclusions are often acquired in handling highly-conflicting informations with D-S evidence theory.Due to this deficiency,the application of evidence theory is severely restricted,thus the current research aims at modifying the original source of evidence.This paper presents a combination method based on Mahalanobis distance,and the original source of evidence is corrected by properly measuring the conflict size.Numerical analysis indicates that,the new combination method enjoys significant performance improvement in dealing with high-conflict situations.
