The concept,the theory and application fields of multi-sensor information fusion are discussed. Based on this,a scheme of multi-sensor information fusion is presented. The multisource battlefield informations are captured and apperceived by using multi-sensor information fusion technology,and the potential targets are detected and identified by information fusion algorithm. Thus,the estimations of target state,battlefield situation and threat can be obtained accurately,which achieves the full dimensional battlefield perception in the future battle.
