The ar thmet c def nes the d stance matr x by the Eucl dean d stance and determ nes the orders of sensor fus on accord ng to the m n mum d stance cluster ng . It may overcome the nfluence of subject ve f actor for the relat onsh p matr x and mprove the object v ty of data fus on . The analys s for the exper ment data shows that the method s very s mple, can avo d los ng the mportant extreme data and eff ect ve data, and has better accuracy.
