Physical Optics Inverse Diffraction,

Abstract

A general method for solving the inverse diffraction problem is presented. It is based on an identity of Bojarski which states that gamma(x) and Gamma(p) are a Fourier transform pair. Here gamma(x) is the characteristic function of the target (gamma = 1 inside the target, gamma = 0 outside), p = (2 omega/c)J, omega is the frequency, J is a unit vector specifying the aspect, and Gamma(p) can be obtained by measurement of the backscattered electromagnetic far field at frequency omega = (c/2)
