Abstract: Aimed at the problem of multi-sensor target recognition on object-level，a new information fusion method is proposed.The method defines the new distance measure.By solving the optimal programming of minimizing the total overall distance measure between the target types and the discriminated target，the weights of indexes are objectively derived.The method of target recognition is given according to the overall distance.The simulation experiment proves that the method is effective and very suitable for the field of multiple objects recognition with multiple characteristic indexes.
