“…Moreover, in a homogeneous medium, the mapping of natural poles {σ m ; ω m } is independent of the target orientation relatively to the excitation (Berni, 1975) and can be used as a discriminatory of targets. Furthermore, among the whole set of these possible poles, only a few of them appreciably contribute to the target response and are thus sufficient to characterize a radar target (Chauveau, 2007-a).…”

Abstract-In resonance domain, the radar scattering response of any object can be modelled by natural poles of resonance with the formalism of the Singularity Expansion Method. The mapping of these poles in the complex plane gives useful information for the discrimination of a radar target, as its general shape, its characteristic dimension and its constitution. In this paper, we use an analogy with resonant circuits modelling to define the quality factor Q of each resonance. Therefore, we propose to characterize the resonance behavior of perfectly conducting targets with this quality factor Q and the natural pulsation of resonance ω 0 . Indeed, this new representation in {ω 0 ; Q} allows to better separate information than the usual mapping of natural poles of resonance in the complex plane. For perfectly conducting canonical and complex shape targets, we present results exhibiting advantages of these two parameters {ω 0 ; Q}.

“…Both the location of items (that support appreciable induced surface currents) concealed on the human body and the nature of these concealed items can be determined by making use of the well known and characteristic ringing that occurs when these items are excited with radiation that matches their resonant frequencies [25][26][27][28][29][30][31][32][33][34].…”

Abstract-The detection and identification of metal items and, in particular weapons, of linear size ≥ 10 cm, concealed upon the human body, is demonstrated as being entirely feasible by using a phased array of suitably ultra wide band transceivers. The complex natural resonances and especially the fundamental resonance, are excited by ultra wide band, stepped frequency continuous wave illumination of the target, using a phased array of antennae to focus the radiation. Broadband illumination of the target with microwave radiation of suitable frequency range (Typically 0.3-3 GHz for handgun sized objects) excites low order complex natural resonances and the late time response of the concealed item can be spatially located using phased array imaging techniques. Further processing of the late time response enables classification of the concealed object, based on the complex natural resonant frequencies of the object, so that threat items such as handguns and knives can be differentiated from benign items such as mobile phone handsets and cameras.
