摘要
针对传统电磁环境可视化中多维信息难以全面定量展现的问题,提出了一种基于多维信息可视化技术的电磁态势展现方法。这种可视化方法没有局限在三维空间框架中进行数据显示,而是将空间转化为一个或几个维度,和电磁环境的其他特征域一起构建多维坐标体系来实现电磁态势可视化。论文提出了电磁环境特征的维度映射模型,并应用了两种多维信息可视化方法:平行坐标系方法和放射坐标系方法,仿真后的可视化结果表明,平行坐标系方法能较好展现电磁总体态势和频谱分布特征,放射坐标系利于特定条件下的信息查找。
The traditional description of multi-dimensional information in electromagnetic environment is always unquantified and incomplete.Thus,a new method to display the electromagnetic situation is proposed in this paper,which is based on multi-dimensional information visualization technology.Compared with traditional methods,the data is not displayed in the 3-D space framework.Instead,the space is transformed into several dimensions,and then become part of multidimension coordinate system,which is composed of space and other spectrum features.To achieve this method,the dimension mapping model of electromagnetic environment features is proposed,based on which the 4-dimension coordinate system for electromagnetic situation is built.And two applications— parallel coordinates and radial coordinates—are used for visualization.Simulation results show that the advantage of parallel coordinates method is revealing the overall situation of electromagnetic environment,and radiation coordinates method is suitable to search special information.
