本文研究数值一致性绕射系数的提取方法。在建立散射模型并确认其散射中心后，用ＦＤＴＤ方法计算散射场，并通过电流加窗方法或联立方程组方法以提取所关心散射中心的一致性绕射系数。金属板边缘的例子验证了这一途径的可行性。最后，用这种方法获得了涂层金属板的一致性统射系数，其结果与阻抗劈的ＵＴＤ结果一致。
In this paper, numerical consistent diffraction coefficient extraction method is studied. After establishing the scattering model and confirming its scattering center, the FDTD method is used to calculate the scattering field and the coherent diffraction coefficient of the scattering center of interest is extracted by the current windowing method or the simultaneous equations method. The example of the edge of a metal plate validates the feasibility of this approach. Finally, consistent cohesion coefficients of the coated metal sheets were obtained in this way, and the results were consistent with the results of the impedance-split UTD.
