Data Fusion In Situation Assessment

Situation assessment is a important part in data fusion, realizing it needs found proper reason algorithm and system model. But those papers published are mostly about theroy, how to establish frondose model is a pivotal question in situation assessment . This paper plots the function of situation assessment, uses two kinds of technology to eatablish situation assessment model, simulates them and analyzes the results. The dissertation is researched as follows:Firstly, the three level situation function model including situation awareness, situation comprehend and future situation forecast is founded, then analyzes every block's function; Analyzes the essential character and reason mode through some instances, concludes the common character of situation assessment and reason frame; then research some algorithms about situation assessment,gives a template matching algorithm.Secondly, eatablishes the situation assessment model based expert system and bayes network, simulates them and analyzes the simulaition results, then discusses the pessible problem if the two methods are used to research situation assessment.Thirdly, the VR_Force technology of MAK compony is implied to build the battle enviorment, then resding the information of entities becomes very easy, thus not only decreases the workload on computer simulation but also makes the effect more clear.Finally, we view VR_Link as a "bridge", it can connects VR_Force with VC, then we do situation reasoning in VC platform, thus provides a common entrance.
