摘要: 用板块法逼近目标表面外形,对物理光学积分离散化,求出每个板块上的散射场,得到目标外形对散射场贡献的三维分布特性,将可视化电磁学与计算机图形学结合,得到了一种确定目标强散射区暨雷达吸波材料涂敷区域的方法,并给出了一些计算结果.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.
