Abstract: In order to efficiently combine highly conflict evidence, this paper proposes a new combination method based on the weighted distance of evidence by using Murphy’s method and Deng’s weighted averaging method. The weight of each body of evidence is determined by using Murphy’s method. The weighted distance between every two evidences is calculated under the modified City Block distance norm, so the support degree of each evidence supported by other evidences can be obtained. After normalizing the general support degree of each evidence as the weight of each evidence, the information fusion process under the Dempster combination rule can be realized. Simulation results show that the new method converges at a faster rate and can recognise the target more effectively and fleetly.
