Abstract: After requirement description methods are researched widely，a description method of operational information requirement based on extended UML is proposed.Both static and dynamic situations of operational targets are described in this method，through which information requirements of prewar and wartime are both satisfied.At the same time，operational function requirement system is established，through which information requirement of our combat units can be analyzed qualitatively and described quantitatively.Finally，a contrast is made between this method and other methods of information requirement description.The information requirement description method based on extended UML is of great significance for clearing up battlefield “fog”，enhancing battlefield clarity，and realizing the automatization and flatness of operational command，control and decision-making.

摘要： 在广泛研究需求描述方法的基础上，提出了一种基于扩展UML的作战信息需求描述方法。该方法通过作战目标的静态和动态描述，满足了战前和作战过程中的敌情信息需求。通过构建作战功能需求体系，对我方作战单元信息需求进行定性分析和定量描述。最后，与其他信息需求描述方法进行了对比。基于扩展UML的信息需求描述方法对于消除战场“迷雾”，增强战场透明性，实现作战指挥、控制、决策的扁平化、自动化具有重要意义。
