Research on Sea Battlefield Data Fusion Method based on D-S Evidential Theory and Event Net

The battlefield data accumulated during the naval formation mission, which shape and content are various for the different detection body, needed to be fused before application to the decision-making support. Aiming at the data fusion problem in sparse information environment, the semantic structure of battlefield situation events for situation assessment was analyzed, and the research framework was designed, and the framework for judging the reliability of battlefield events was set up. Based on this, the model of event reliability was established, the algorithms of single event reliability calculation and multi event fusion analysis were proposed, the effectiveness of the method was proved by the empirical analysis.
