Abstract: Battlefield environment, filled with all kinds of devices with frequency electromagnetic signals, results in complex and rapidly changing electromagnetic environment. And the uncertainty brought by the complexity and the time variability not only makes it hard to predict the result of a war, but also leads to higher requirements for the current electromagnetic visualization platform serving for decision. To satisfy the visual needs for the electromagnetic spectrum data in the battlefield environment, the electromagnetic spectrum trend was designed in the perspective of temporal, spatial, frequency, and the energy domain. Four situations were proposed: equipment frequency radiation situation, spectrum resource state situation, the regional energy distribution situation and the interference situation. The electromagnetic spectrum visual simulation platform on VS2008 in C++ aided with ArcGIS, OpenGL, TeeChart was developed.

Key words: battlefield environment, electromagnetic, spectrum, visualization
