利用长旋转椭球矢量波函数和涂覆椭球表面的阻抗边界条件，给出了平面电磁波沿主轴方向入射时涂覆长旋转椭球散射场的解析表达式及其远场双站散射截面的计算公式和计算结果，本文的主要结论是：不仅几种典型形状理想导体目标对平面电磁波的散射场可用解析公式表示，这些形状的涂覆目标的散射场也可用解析公式表示。

By employing the spheroidal vector wave function expansions for the incident and scattered fields and the impedance boundary conditions on the coated surface,an analytic solution of the plane electromagnetic wave scattered by a coated prolate spheroid for axial incidence is derived,and numerical calculations are obtained.
