Analysis of back polarization scattered by finite length conducted cylinder

应用物理光学法 (PO)和增量长度绕射系数法 (ILDC)推导并计算了有限长导体圆柱的后向散射极化矩阵 ,进而分析了目标的特征极化参数和入射角之间的关系 ,并给出相应的数值仿真结果 。

With the method of physics optics (PO) and increasing length of diffraction coefficients (ILDC) for edge scattering, the formulas of the back polarization scattering matrix (PSM) for finite length conducting cylinder was presented. According to the PSM, the characteristic parameters that change with the incident angle were analyzed. The result of numerical simulation shows that the presented scheme may be helpful to identify an object by the polarization information.
