摘　　要：在文中,对三面角反射器进行仿真,用PML/ABC来截断有限元计算域,求得三面角反射器的单站雷达散射截面,并与其他方法的计算结果进行比较,结果证明,FEM/PML/ABC法对于三面角电磁散射分析是有效的。This paper presents the monostatic radar cross section of the trihedral corner reflector by terminating the un- bounded finite clement computing region with the combination of PML and ABC and the solution is compared with the measured solution which demonstrates that this approach is effective for electromagnetic scattering of the trihedral cor- ner reflector.
