Currently, information distribution based on publish/subscribe is widely used in battlefield situation information sharing, where the theme-oriented or content-oriented ideas are mainly adopted. However, information requirements of the same combat unit are different when executing different missions. And traditional publish/subscribe based information distribution is not competent enough to meet the dynamic information requirements of combat units that are closely related to missions. We propose a mission-oriented dynamic distribution method of battlefield situation information with a feedback mechanism. Where a structured general concept model is designed to realize a consistent representation of heterogeneous battlefield information from different information systems, based on which, a unified information space is built. A matching strategy between missions and classified battlefield situation information based on rules is designed to realize mission-oriented customization of information. An information feedback mechanism based on content and semantics is proposed to realize information correctness and integrity verification based on the applied-logic of missions, as well as feedback information generating. Theoretical analysis shows that, feedback-based information distribution can provide required information for different combat units dynamicly, at the same time, it is conductive to achieve mission-oriented targeted acquisition of situation information and to realize the complement of battlefield situation information space.
