基于本体的电磁环境描述与仿真概念模型

Ontology-based Description and Simulation of Conceptual Model in Complex Electromagnetic Environment

针对战场电磁环境复杂、多维、时变等特点及电磁环境仿真概念模型表示关系不够清晰、容易产生冗余及可扩展性差等缺点,提出了基于层次关系的复杂电磁环境综合分析方法,并在电磁环境分析描述基础上提出使用本体来表示电磁环境的概念模型,给出了战场电磁环境仿真概念模型本体设计标准及战场复杂电磁环境仿真的主要实体和实体间的交互关系。最后运用基于OWL的战场电磁环境本体描述方法实现了雷达最大探测范围的描述,结果表明,该方法对战场复杂电磁环境的描述与仿真、电磁环境领域知识的获取、重用、共享和组织是有效的,同时对复杂、多维的其它领域描述起到了指导作用。

For complex, multidimensional, time-varying characteristics of battlefield electromagnetic environment. Currently it is not clear that electromagnetic environment simulation conceptual model represents the relationship, and prone to generate the concept of redundancy and scalability poorly and other shortcomings. It is proposed that complex e- lectromagnetic environment comprehensive analysis method based on a hierarchical relationship. And describes the elec tromagnetic environment analysis and represents the electromagnetic environment simulation conceptual model based on the use of ontology. Then gives battlefield electromagnetic environment simulation conceptual model ontology design standards. And complex battlefield electromagnetic environment simulation and interaction between the principal entity. Finally, based on the language of the battlefield electromagnetic environment OWL ontology method to achieve maximum detection range of the radar description. The results show that it is effective to the description of complex electromagnetic environment and simulation of the electromagnetic environment knowledge acquisition, reuse, sharing and organization. While complex, multidimensional description of other areas has played a guiding role.
