摘　　要：本文提出了一种用于分析电磁散射的多层Ｚ缓冲器技术，它使计算机图形学与电磁散射分析相结合，能有效地解决复杂物体电磁散射分析中的隐藏面消除问题和多次散射计算的射线跟踪问题，从而使复杂物体电磁散射的分析和计算更为精确，而且使多次散射计算的射线跟踪速度加快．计算机模拟计算结果表明，提出的新技术是有效的．本文的多层Ｚ缓冲器技术可应用于其它研究领域．In this paper, a new technique - multiplaten Z-buffer technique - is presented.This technique combines the computer graphics with the analysis of the electromagnetic scattering. Employing the CAD-geometry based on the multiplaten Z-buffer technique,we can solve thehidden-surface elimination and the ray tracing problems,which are two formidable tasks in theradar cross section(RCS)analysis of the complex body. Some calculation results are given and compared with the experimental results. The comparisons show that our technique is effective. In addition,this technique can be applied to other research domain.
