摘要:

为了将不可见的电磁环境直观展示给指挥人员,提出了一种在虚拟环境中体可视化电磁环境的方法. 采用LongleyRice电波传播模型计算三维电磁环境体数据,并采用硬件加速的直接体绘制方法,通过坐标转换在虚拟环境中及时绘制电磁环境体数据,通过颜色映射工具分类显示出不同强度的电磁环境. 实验结果表明,该方法可及时展示复杂电磁环境内部细节,对于电磁装备系统部署规划也有一定帮助.

Abstract:

In order to represent the invisible electromagnetic environment to commander, the volume visualization based approach of electromagnetic environment in virtual environment is proposed. First, this approach uses the LongleyRice radio propagation model to calculate 3D electromagnetic power volumetric data. And then the data is rendered on virtual environment using coordinate transformation based on hardwareaccelerated volume visualization. Finally, electromagnetic environment of different power is classifiably represented using color mapping tool. The results of the experiment show that this approach can visualize the inner detail of electromagnetic environment, and provide decision supporting and electromagnetic equipments planaiding for users.
