摘　　要：通过分析复杂电磁环境的产生机理,研究了电磁源选择、电磁波通视和电磁辐射空间分布等复杂电磁环境仿真所需的关键技术。提出了信噪比空间的概念并建立了电磁环境复杂度度量方法和度量标准。在此基础上建立了一个复杂电磁环境仿真模型。该模型根据电磁源的动态变化计算其辐射分布,并以信噪比空间为度量基础提供电磁环境的复杂度评价,为战场辅助决策提供必要条件。By the analysis of complex electromagnetic environment, the three key technologies, classification of electromagnetic sources, electromagnetic wave visibility and spatial distribution of electromagnetic radiation are studied.A SNR space is defined.The complexity metrics algorithm and standard is established.On the basis, a complex electromagnetic environment simulation model is modeled.In the model, the radiation distribution of the sources is computed and the complexity of electromagnetic environment is provided.The model-based training system is used to support decision-making training in the complex electromagnetic environment.
