| Abstract: | In this paper, based on the Bojarski-Lewis relation, the 3D inverse scattering and imaging for the conducting objects with arbitrary shapes by using the limited frequency aperture is studied. The corresponding rules and algorithms such as the selection of the frequency domain aperture, the high precision computation of F-function and the envelope pick-up are discussed in detail. Finally, by using the scattering data for some typical conducting objects obtained by the physical optic (PO) method, the 3D inverse scattering images for these objects are achieved, which are all well matched with the original objects. |
