| 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. |
