摘要 本文用FDTD方法在散射目标近区对口径面天线与目标的相互影响进行了分析研究,在圆柱坐标系下以轴对称数值模型为例,用FDTD方法得出了散射目标电尺寸、目标与口径面天线的距离大小对天线口径面的场分布之影响的数值结果;同时获得了散射目标表面物理光学近似计算散射电流的应用范围. In this paper, the interaction between scatterer and aperture antenna situated in the scatterer' s near zone is studied and simulated by using the FDTD method. The numerical model with axial symmetry in cylindrical coordinates is chosen as an example,for different distance between the scatterer and the antenna,the numerical results of electric field distribution on the antenna's aperture are obtained. The application range of physical optics method in computing surface current on the scatterer is also given . The validity of this method is verified by mode theory in the circular waveguide.
