摘　　要：科学计算可视化日益与各学科相结合 ,产生新的研究方法。在复杂目标电磁散射研究中 ,目标的几何建模和雷达散射截面 (RCS)计算结果的分析在目标电磁散射分析中越来越重要 ,利用多种样条曲面进行复杂目标精细几何建模 ,采用GRECO(图形电磁学 )法计算目标的RCS值 ,从而提高电磁散射计算的精度 ,并对RCS计算结果进行可视化处理 ,使计算结果直观且易于分析。The visualization in scientific computing is connected with various subjects increasingly, and new research method is produced. In the electromagnetic scattering research of complex object, the geometric modeling and the analysis of radar cross section (RCS) calculation are very important in the analysis of object electromagnetic scattering. In this dissertation, various spline surfaces is used to fit geometric modeling carefully for complex object, GRECO (graphical electromagnetic computing) is used to calculate the object's RCS, the precision of electromagnetic scattering computing is increased accordingly. The computing result is intuitionistic and prone to analysis, because the RCS computing result is put to visualized.
