The resonance theory of scattering, is applied to radar backsacttering from penetrable targets in an attempt to solve the inverse scattering problem. This means the extraction of sufficient material-composition information from the electromagnetic scattering amplitudes of the returned echoes, to permit target identification. The authors illustrate the principle for the case of a conducting spherical target coated with a dielectric layer. The principle of the method is to use the resonances contained in each of the partial waves making up the radar cross-section for material characterization purposes. In the high frequency region, the spacing between consecutive overtones becomes uniform, and is related to the dielectric constant of the coating.
