摘要:

电子设备会向空间辐射电磁波，研究电磁波在空间的分布特性,在民用和军事领域都具有重要的意义。提出了一种电磁波在地面上覆盖范围的快速可视化方法，将方法分解为6个主要的功能流程：预估电磁覆盖区域、提取局部高程网格、计算网格点场强值、网格点着色、生成纹理图片和纹理贴图。基于计算机图形学和地理信息系统的相关原理，分析了每个功能流程，主要从可视化的角度讨论了其中的技术特点。通过仿真实验验证了方法的正确性和有效性。

Abstract:

Electronic equipments can emit electromagnetic waves into 3D space. The research on distribution of electromagnetic waves in space is important in civil and military fields. This paper presents a quick method for drawing electromagnetic waves on terrain. The method contains six functional procedures: evaluating coverage region electromagnetic waves, drawing local terrain mesh points, calculating the power of electromagnetic waves at the mesh points, coloring the mesh points, generating texture image, and overlapping the texture image on terrain. The paper mainly analyzes the characteristics in detail of every procedure based on computer graphics and geographic information system. The correctness and effectiveness of the proposed method are validated through simulation experiments.

Key words: electromagnetic coverage 3D visualization parallel computing geographic information
