Research on the Technology of Electromagnetic Information Modeling and Visual Analysis.

The visualization of electromagnetic information is a hot topic in recent decades, which displays the invisible data in an intuitive way to help the users to gain an overall view of the electromagnetic environment of the electromagnetic equipment. In this paper, a visual analysis framework is proposed which is composite of unified and standardized description of data, visualization methods and interactive visual analysis. The electromagnetic information is formed to grid data from the communication electronic equipment and radar firstly and then the visualization methods such as isosurface rendering and direct volume rendering are overviewed. The interactive visual analysis technology is also studied to help the users to research the features of the electromagnetic environment in an intuitive way.
