摘要：
The modified extended physical optics (EPO) method, which assumes the physical optics current properly over the entire surface of conducting scatterers, is applied to the inverse problem of target profile imaging. The usefulness of the modified extended physical optics method for the direct backscattering problem is first demonstrated. Then this method is applied to the inverse problem by introducing the phase factor determined iteratively for the shadowed portion of the target, and by performing the Fourier transformation of the backscattered field in the frequency domain. As an example, the inverse profiling of nose-on spheroids, including a sphere, is tested and discussed. © 1990 IEEE
