摘要

本文给出推广的物理光学近似下理想导体目标的Ｆｏｕｒｉｅｒ衍射定理，其形式与介质目标的相应关系式十分相似，利用这一关系式可以由测量直线上散射场分布重建二维理想导体目标Ｆｏｕｒｉｅｒ域的空间谱值。通过简单例子讨论了这一关系式的适用性。

Abstract

Based on the extended physical optics approximation

we obtain the Fourier diffraction theorem for a perfectly conducting object

which is quite similar to the one for a dielectic object derived under the Born or Rytov approximation. This identity relates the object characteristic function with the scattered fields over a measurement plane in Fourier domain.Therefore

it can be used to reconstruct a perfectly conducting target from the scattered dara. The availability of the itientity is exemplified by a circular cylinder case.
