Visual computing for scattered electromagnetic fields

Abstract

In this paper, an innovative procedure is presented to simulate and visualize the scattered electric field from a target illuminated by radar waves. The propagations of radar waves are computed by using a ray-tracing method. Then the scattered field is computed at receivers which are located in concentric spheric surfaces surrounding the target. The scattered electric field is converted into RCS values and illustrated by using volume rendering and other graphical techniques. Compared with conventional radar simulation methods, our procedure produces more information but consumes less computational costs. The simulation results are better explored by using improved graphics techniques. Hence the scattered field is more comprehensible. © 2009 Springer-Verlag.
