摘　　要：分析了战场信息以及信息需求的特征,从用户的角度出发,提出了基于信息熵的战场信息价值度量模型,有助于指挥决策人员整体、快速地把握战场信息对作战的支撑情况,促进信息优势向决策优势转化。模型以满足用户的信息需求为出发点,聚焦战场信息的使用价值,建立了"目标/任务-信息主题-主题因子-概率分布-信息价值"的分析框架,并基于信息熵和贝叶斯理论,计算上述分析框架下战场信息的实得信息,由此获取战场信息的使用价值,实现战场信息价值的度量。This paper first analyzes features of battlespace information and its demand,and then presents a judgment model for the value of battlespace information from the user’s point of view,based on the theory of information entropy.The model could help commanders to hold the whole situation quickly about how well the battlespace information in support of the warfare,and promote information superiority to decision superiority.The model concentrates on the value of battlespace information on satisfying users’information demand,builds an analytical framework in the form of"objective/mission-topics of informationfactors of topic-probability distribution-value of information",computes the real information quantity with the entropy and Bayes theory under the above analytical framework,and then gets the value of battlespace information.
