Abstract

It is with great significance to improve the speed of analysis and visualization of electromagnetic situation. However, The calculation amount of wave propagation involving numbers of radiation sources to form the electromagnetic situation is very large, and directly calculation is time-consuming. In this paper, the raster database is introduced into the calculation and storage of electromagnetic situation. Then, the corresponding isoline tracing algorithm for regular raster structure is given, as well as the isoline smoothing and filling algorithm. At last, the calculation efficiency of the developed method is compared with the previous method under the same electromagnetic environment. In the developed system the calculation time can be shortened from more than 17 hours to 20 minutes, and 100 radiation sources in the application scenario can be calculated and visualized in 1 minute. All of this show that the electromagnetic situation raster database can significantly improve the system running speed and the data application efficiency.
