Computation of scatter characters of media target based on GRECO

  • Among all the methods of computing the scatter characters of radar targets, graphic electromagnetic method and ray tracing technique are two valid ways in high frequency.A valid method was presented to combine these two ways. First, with the help of illumination model and automatic hiding in OpenGL, the shape of media target was shown on screen. The color and position information of each pixel could be obtained from the buffers to compute the first scatter effect and then the position and normal vector information was taken as the start point to calculate the multi scatter effect by the ray tracing technique. At last, adding the two components leads to the total radar cross scatter. The simulation of cylinder and sphere proves the validity and effectiveness of this method.
