摘　　要：本文介绍了利用谱域迭代方法计算理想导电腔体后向散射和RCS的方法,揭示了波谱在腔体内传播的过程。针对腔体截面形状的不同,给出了应用等效电磁流法解决腔体边缘绕射对口径场影响的方法。最后通过算例验证了方法的正确性。In this paper,the method of calculating the backscattering and RCS of an ideal conducting cavity by using the spectral domain iteration method is introduced,and the propagation process of the spectrum in the cavity is revealed.According to the different cross-section shapes of the cavity,the equivalent electromagnetic current method is used to solve the influence of the cavity edge diffraction on the aperture field.Finally,the correctness of the method is verified by an example.
