This paper describes an approach to model the impulse response of a dielectric target below a half-space using a time domain deconvolution technique. The complex natural resonances (CNR) of the target are extracted from the time domain impulse response using a matrix pencil method and can be correlated with the target's physical properties. An automated E-pulse scheme has been used to discriminate changes in the physical properties of target. The discrimination performance is calculated quantitatively by using an energy discrimination number (EDN) and discrimination ratio (DR). This technique can ultimately be used as a diagnostic tool in detection and discrimination of an unknown target inside a half-space.
