Abstract:

The visualization of electromagnetic information, especially the visualization of radar coverage, is an important issue in virtual battlefield environ ment. But now most of the research is just for 2D and the research in 3D is limited inspeed. So a new hardware-accelerated 3D visualization method is pu t forth in this paper. Based on the 3D data field of radar Electromagnetic （EM） loss, a hardware-accelerated algorithm is designed to extract the isossurface for an isovalue, which corresponds to the radar coverage for a given target of one RCS. Then this isosurface is represented into the digital bat tlefield. In the experiment on popular PCs specific to typical radars, the 3D radar coverage is vividly visualized in time, which overcomes the flaws of  the former non-intuitive 2D and slow 3D methods, and provides an excellent decision-making support for users.
