The traditional conflict measure between attribute information can’t objectively give a quantitative description about their dissimilarity when the information quality is relatively low resulting from sensors’ poor identification performance. So a new conflict measure is defined, which can nicely distinguish between the attribute information from targets of the same type and that from targets of different type. Taking the new conflict measure as its basis, the correlation decision for attribute information is implemented with multi-dimensional assignment algorithm. Theoretical analysis and simulation experiment results show the effectiveness of the proposed attribute information correlation algorithm based on the new conflict measure.
