| Abstract: | The complicated target is approximated by amounts of patches.By discreting integral equations of physical optics,the scattering fields on each patch can be calculated.Thereafter the 3 D scattering property of a complicated target versus the contour of the target can be analyzed with the knowledge of the scattering fields.By combining the visual electromagnetics and computer graphics,the method to distinguish the stronger scattering area based on the 3 D distribution of scattering energy caused by a complicated target is developed.Some results have been obtained by using this method. |
