摘要

本文采用FMIR-MoM与质心细分正交相结合的方法对PEC目标的宽带RCS进行分析。通过使用FMIR-MoM，可以快速获得宽频段内的电磁特性。该方法不需要更小的频带分割，而在插值技术中则需要更小的频带分割。内存需求与后面的版本相当。然而，在处理奇异项时，还需要进行特殊处理。阻抗填充采用了基于质心细分的正交法，避免了奇异积分的产生。通过两个数值算例验证了该方法的精度。

Wideband RCS analysis of PEC objects by combining FMIR-MoM with barycentric subdivision-based quadrature technique

In this paper, the combination of FMIR-MoM with barycentric subdivision-based quadrature is utilized to analyze the Wideband RCS of the PEC objects. By using the FMIR-MoM, the electromagnetic properties over a wide frequency band can be quickly obtained. In this method, smaller frequency band division is not needed while it is required in the interpolation techniques. The memory requirement is comparable to the later ones. However, the special treatment is yet needed when dealing with the singularity term. The barycentric subdivision-based quadrature is applied in impedance fill-in, in which the singular integral can be avoided. Two numerical examples are included to test the accuracy.
