摘要: 建立复杂目标几何外形的数学模型,对独立目标使用外法向判断可见面元,对复杂目标使用Z-buffer算法处理自动遮挡问题.通过求解电磁场边值问题求解目标表面的等效电磁流分布,并求解散射强度的三维分布特性.仿真计算结果被若干测试结果验证,证明该方法的精度较高、实用性强、可靠性好.算法可以直观地显示目标散射强度的三维分布图.

Abstract: By setting up the numerical model of a complicated target, applying outside normal vectors of visible patches of each individual body, and useing Z-buffer algorithm to solve shielding between multi-bodies of complicated targets, the three dimensional scattering problems are analyzed successfully. The currents on the surface of the targets are calculated by solving EM boundary problems. The results obtained by the algorithm are verified by tested results. The method is proved to more accrete, practical, and reliable. The three dimensional scattering distribution could be given in visible way.
