Based on analyzing the electronic warfare systems and the engaging processes, the method hierarchizing object, class and type was introduced,and the elements in electronic warfare system, such as entity, state,attribute,and relation, etc. were generalized. And then the ontology for electronic warfare was brought forward. At last, the ontology was applied in the example ship confronting approaching missile in which general formalization about electronic warfare simulation models was researched. The ontology makes for ensuring the basic attributes in electronic warfare,constructing the models of electronic warfare in advance simulation systems, which all are basics for bottoming the combined distributed electronic warfare simulation systems.%在分析电子战系统和电子战交战过程的基础上,采用对象、类、类型层次式的方法,首先概括电子战系统中的实体、状态、属性、关系等要素,然后提出电子战系统的本体论,最后将本体论应用到单舰反导的实例中,研究电子战系统仿真模型的通用形式化.该本体论有助于确定电子战系统及其交战过程的本质属性,构建先进仿真中电子战系统的计算模型,为建立可组合的分布式电子战仿真系统奠定基础.
