In order to solve the problems to conflict evidence combination in standard D-S theory,this paper proposed a novel approach based on evidence weighted.Firstly,it mapped basic probability assignment(BPA) to a point in the multidimensional space.Then,it computed the Euclidean distance for two arbitrary points and obtained the weight of every evidence.After weighted averaging the evidence by constructing the Huffman tree,it used the D-S combination rule to achieve information fusion.The validity of the approach was demonstrated by simulation example.The proposed approach can solve the problem to conflict evidence combination.
