| 摘 要： | 介绍一致性绕射理论等效边缘电磁流（ＵＴＤＥＥＣ）的公式。该公式是基于Ｍｉｃｈａｅｌｉ的半平面等效边缘电磁流（ＥＥＣ）表达式，用平截的劈增量条计算等效边缘电磁流。这样可以消除以往计算中的虚假奇异点，对任意入射和观察方向均有良好的性态。本文用此方法计算了方板和梯形板的双站散射，并与高阶等效边缘电磁流的结果比较，具有良好的精度。

| Abstract: | New expressions for uniform physical theory of diffraction equivalent edge currents (UTDEEC) are derived in this paper. These expressions, which are based on the Michaeli's physical theory of diffraction equivalent edge currents, derived for truncated incremental wedge strips.These EEC do not have singularity problems of the previously reports. They are well behaved for all directions of incidence and observation. Bistatic RCS of a square plat and a echelon plate are calculated by above method in the paper, which is in good agreement with the results of high order equivalent currents. |
