Research on Visualization of Electromagnetic Information in Virtual Environment

In the article we research the visualization technology of electromagnetic information. It focuses on the drawing of the signals and multi-path signals transmission in the virtual battlefield environment. Firstly, we use the OpenGL functions to complete the drawings of the time domain signals and spatial beam patterns. Secondly, we build the propagation model which is based on the theory of geometrical optics and realize the visualization of multipath phenomenon. Finally, those drawings are inserted into the virtual battlefield environment built by Vega. Accordingly, the commanders could be able to get electromagnetic battlefield information they need vividly and intuitively, which could make them determine more promptly.
