摘要:

计算物体的雷达散射截面始终是电磁散射研究的重点,精确快速地求解RCS问题是其研究的主要方向。文中介绍了电磁场有限元,以及基于有限元法的HFSS仿真软件应用,重点分析了HFSS在求解过程中边界条件、网格剖分等对精度的影响,结合计算实例,其结果证明了有限元法计算复杂物体RCS的正确性。

Abstract:

Calculation of objects' RCS has been the focus of study of electromagnetic scatting with accurate and efficient solution to RCS being the main direction of research.This paper introduces the electromagnetic field Finite Element Method (FEM) and the FEM based HFSS simulation software.Emphasis is put on the analysis of the effect on accuracy of HFSS boundary condition and mesh grading in the solution process,and calculation examples are offered.Results show the correctness of FEM for objects' RCS.

Key words: FEM;RCS;HFSS;auto adapted grid
