文章给出了一种改进的等效电磁流公式，该公式是在Ａ．Ｍｉｃｈｅａｌｉ的表达式的基础上得出的。当观察方向位于Ｋｅｌｌｅｒ锥上时，改进的Ｄ＿ｅ，Ｄ＿ｍ表示式可化简为Ｋｏｕｙｏｕｍｊｉａｎ￣［１］的绕射系数，等效电磁流的表达式同Ｋｎｏｔｔ和Ｓｅｎｉｏｒ￣［２］的表达式完全一样。在阴影和反射边界上，改进的等效电磁流表达式具有一致性。
The article gives an improved equivalent electromagnetic flow formula, the formula is in A. Based on the expression of Micheali. When the observation direction is on the Keller cone, the improved D_e and D_m representations can be reduced to the diffraction coefficients of Kouyoumjian ~ [1]. The equivalent electromagnetic flow has exactly the same expression as Knott and Senior ~ [2] . On the shadow and reflection boundaries, the improved equivalent electromagnetic flow expression is consistent.
