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.
