基于APM模型的电磁波三维可视化研究与实现

电磁环境可视化是战场可视化的关键内容,针对电磁环境复杂性的特点和目前电磁环境可视化研究多局限于二维平面且不能表现等值线、等值面内详细情况等问题,论文对于固定频率的电磁波,利用了APM（Advanced Propagation Model）模型计算出电磁环境垂直剖面上的基础数据,利用旋转把它扩展到三维数据场,然后在Matlab中利用三维散点图实现电磁数据场的立体三维可视化,同时也实现了等值面绘制,把电磁波的内部和边界很形象地表现出来,更加全面地展现了电磁环境.

3D Visualization of Electromagnetic Wave Based on APM Model

Visualization of electromagnetic environment is the key content of battlefield visualization. Concerning about the complexity of electromagnetic environment and that the researches in this field are limited to the two-dimensional plane, which cannot express the details inside the contour or contour surface, the APM（Advanced Propagation Model） is used to produce electromagnetic environment data on fixed frequency to extend it to 3D data by rotating, then 3D scatter plot in the Matlab is used to realize stereoscopic 3D visualization of electromagnetic data field, rendering the isosurface at the same time. Interior and boundary of the electromagnetic waves is shown very vividly, and electromagnetic environment is shown more comprehensively.
