The electromagnetic environment simulation and visualization analysis system integrates the battlefield electromagnetic signal environment simulation function and the electromagnetic signal visualization analysis function. On the one hand, according to the composing elements of electromagnetic environment and their changing characteristics, two signal models of coarse particles and fine particles are established, as well as the signal spatial propagation model; and the electromagnetic signal environment dynamic simulation is realized based on these approaches. On the other hand, through computer graphics, image processing technology and high performance computing technology, the 3D display of battlefield electromagnetic situation and the visualization analysis of electromagnetic signal environment are realized. The functions of the system, the overall structure, the software structure, the hardware structure and the workflow are discussed, and an application of the system is introduced. From the application effect, the system can be used as a simulation tool for EW officers and EW equipment operators to conduct battlefield electromagnetic situation analysis and electronic reconnaissance intelligence analysis training.
