| 摘 要： | 本文研究了高频条件下一个三维新月形导电物体的电磁散射远场的计算问题。在计算中我们根据物理光学和Fock理论得到散射体表面的等效面电流分布,并引入一沿边缘的线电荷分布以计入边缘的贡献。计算结果用于散射体轮廓的投影重建获得成功。

| Abstract: | The calculation of the scattered far-zone EM field produced by a crescentlike three-dimensional conductor under HF approximation is studied. The equivalent surface current distributions used in the calculation are obtained from the physical optics and Fock's theory. To take account of the contribution of the edge, a line distribution of charge along it is introduced. The calculated field data are applied to reconstruct the contour projections of the scatterer successfully. |
