基于知识工程的电子战知识模型设计与应用

 在电子对抗设备设计过程中，为了实现对已有知识的继承、管理、共享与重用，降低电子战系统在概念设计阶段的设计难度，缩短研发耗时，针对电子战系统在概念阶段方案设计过程中的复杂性及其涉及的知识繁多的问题，以广泛应用的数字接收机为主要研究对象，结合知识工程理论，建立结构化、标准化的电子战系统的知识模型，并以此模型为标准阐述建模的方法与准则.通过将所有知识模型用知识工程系统进行管理，达到对已有知识的继承、管理和共享的目的.这样，知识工程系统在知识模型的支持下，可向系统工程师提供多种备选概念设计方案并通过重用知识模型进行方案验证，实现对已有知识的重用，最终达到已有知识对电子战系统在概念阶段方案设计的支撑.

EW knowledge model design and application based on knowledge engineering

In order to realize inheritance, management, sharing and reuse of existing knowledge, reduce the design difficulty of electronic warfare system in the conceptual design phase, and shorten development time in the design process, problems like the complexity of concept design and the variety of knowledge involved in the process were directed. The widely used digital receiver was researched. Combining the knowledge engineering theory, a structured and standard knowledge model of EW system was established which were used as an criterion to explain the modeling method and standard. Through managing all the knowledge model using the knowledge system, the inheritance, management and sharing of existing knowledge were realized. In this way, with the support of knowledge model, the knowledge system could provide various design schemes and verify itself by reusing the knowledge model and realize the reuse of existing knowledge. Finally, the goal of supporting the EW system concept design with existing knowledge achieved.
