Extended E-pulse technique for discrimination of conducting spheres

Abstract

Abstmcf-The study presented is on the influence of forced-E-pulse duration in the discrimination capacity of the E-pulse technique, applied to sphere targets. This analysis allows three ranges of E-pulse durations to be considered and the obtaining of an optimum duration of the forced E-pulse. The results obtained allow the discrimination technique to be extended in order to determine if the radius of an "unknown" sphere is longer or shorter than the radius of the "expected" one.

Performance analysis of the LS Prony method for estimating parameters of damped sinusoids

“…It has been repeatedly demonstrated that target recognition is possible using the natural frequencies of the target. There has been considerable work published on radar target recognition using the natural frequencies [45–63].…”

“…The K‐pulse technique [47–50], the E‐pulse/S‐pulse technique [51–58], higher order statistical approach [59, 60] and likelihood ratio test scheme [61] have been developed as target recognition techniques based on the natural frequencies of the scatterer. All these methods use the late time part of the time‐domain response.…”

“…Chen et al proposed the theory of the E‐pulse/S‐pulse for target recognition [51–58]. The E‐pulse radar target recognition scheme is a resonance cancellation technique grounded in the late time behaviour of the transient scattered field.…”

Identification of an unknown dielectric target in a half‐space using the E‐pulse technique

“…The E-pulse scheme is essentially based on annihilating the CNRs present in the scattered signal by matching the CNRs, with which the E-pulse is constructed, with the CNRs of the target. Equivalently, in the time domain, when the synthesized E-pulse is convolved with the late time target response a zero response in late time results [Mooney et al, 2000;Gallego et al, 1993;Stenholm et al, 2003;Baum, 1999aBaum, , 1999b. The relevance of this work is that we are exploring the possibility of using resonance based methods to detect the unknown dielectric target embedded below a planar interface.…”
