Research on Visualization of Radar Beam Considering Virtual Environment Effect

In a virtual battlefield environment, the 3D visualization of the abstract information of radar beam under the environmental influence of the terrain and weather is the current development trend of the visualization of electromagnetic information. In this article, we have designed two methods by the OpenGL function to complete the drawing of the spatial beam pattern that is inserted into the virtual battlefield environment. And then we combined the stereoscopic concept with the research, and studied the information visualization methods of the radar beam that were under the influence of different environmental factors with the premise of that the radar beam parameters and the terrain elevation data and other relevant parameters were acquired. At last, the users could be able to get electromagnetic battlefield information they need vividly and intuitively, which could make them determine more promptly.
