许多降低物理光学(PO)计算成本的技术已经被开发出来。在本文中，我们介绍了计算PO中辐射积分的技术，其计算量与频率无关。以菲涅耳区数为判据，对辐射积分进行局部化和分割。将该方法应用于二维导体条形和矩形柱体的单站雷达散射截面(RCS)的PO计算。我们在计算时间和精度之间找到了很好的平衡。
Many techniques to reduce the computational cost of the physical optics (PO) have been developed. In this paper, we introduce the technique for evaluation of radiation integrals in the PO, whose computational loads become independent of the frequency. Fresnel zone number is used for the criterion to localize and divide the radiation integrals. The proposed method was applied to the PO computation of the monostatic radar cross section (RCS) for the 2-dimensional conducting strip and rectangular cylinder. We found the good balance between the computational time and accuracy.
