复杂电磁环境建模与可视化研究在民用通信、军用电子战领域的应用不断发展，准确、科学、直观地描述复杂战场电磁环境，对于指挥人员把握战场态势，作出准确判断、科学决策，意义重大。以此为背景，重点研究了雷达辐射源探测范围及空间多辐射源形成的空间合成场强，建立了雷达辐射源探测范围的数学模型，推导了空间多辐射源场强合成算法；提出了虚拟战场环境的快速构建方法，并给出了仿真系统的设计框架；结合混合采样的雷达探测范围面绘制方法，在虚拟战场仿真平台，实现了自由空间及干扰环境下雷达辐射源探测范围三维可视化，并利用区间映射的办法，结合OpenGL强大的色彩渲染能力，实现了多辐射源空间合成场强的态势展示。%With the continual development of modeling and visualization in complex electromagnetic environment in civil communication and the field of military electronics, complex electromagnetic environment can be described scientifically and accurately. It is also of significance for commanders to make precise and scientific decisions on the battlefield. In this context, this paper mainly researches the detection range of radar radiation and the synthesis of field strengths of several radiation sources, building corresponding mathematical models and presenting methods of field strength synthesis and rapid construction. Then this paper achieves 3⁃D visualization of free space and radar ra⁃diation under complex interference environment with simulator system design block diagram, And it accomplishes situation visualization of the synthesis of field strengths of several radiation sources using the method of interval map⁃ping with the help of OpenGL′s powerful Blend func.
