| 摘要: |
| 针对矩量法(MOM)不能有效求解大尺度粗糙介质表面散射特性的问题,采用基于物理的双网格法(PBTG)快速计算了高斯粗糙海面的散射特性,对比了不同矩阵维数下的求解时间,研究了水平、垂直极化下粗糙海面的散射增强现象。通过与矩量法的比较,证明了PBTG法的高效性。 |

| Abstract: |
| The classic method of moment(MOM) can not calculate the scattering characteristic of large-scale rough surface,in view of this problem,the scattering effect of Gauss rough sea surface is calculated quickly with the physics-based two-grid(PBTG) method.The calculation time for different matrix dimensions is compared.And the scattering enhancement effects of rough sea surface are studied at plane-polarization and perpendicularity-polarization with this method.The comparison between MOM and PBTG methods proves the efficiency of PBTG method. |
| Key words: rough sea surface,scattering characteristic,scattering enhancement effect,physics-based two-grid(PBTG)method |
