摘要
针对球面波入射和非均匀照射等近场电磁散射特征,根据表面反射及边缘绕射机理,推导给出了金属平板定标体RCS的近场修正公式;修正的近场RCS结果与矩量法计算结果吻合较好,适用于近场测量时的RCS定标,可有效减少其标定误差。
A set of revisory formulate were derivated to revise near field RCS of metal plate scaler.The revision based on mechanism of surface reflection and edge diffraction,and spherical and non-uniform incident EM wave were taken into account.It showed that the revised near field RCS agree with that obtained by MoM.The revision can be used for calibration of RCS meas urement in near field and decrease the calibration error.
