Theoretical aspects of target classification: Physical optics and radon transform methods
Abstract
Target classification is set up as a multidimensional inverse scattering problem for electromagnetic waves. The target is considered to be of compact support residing in a media with constant wave speed. The scattered field produced by a prescribed incident field is represented by its equivalent sources in terms of Huygens' principle: for the sake of simplicity, the inversion of this representation of the physical optics or weak scatterer approximation linearizes the inverse problem resulting immediately in an inversion formula for the characteristic or singular function of the scatterer if the scattered field is measured as a function of frequency  or as broadband transients  on a closed surface sufficiently remote from the target in an either bistatic or monostatic experimental arrangement.
