The problem of detecting and localizing 'thin' metallic scatterers from electromagnetic scattered field measurements is addressed. The scatterers are assumed to be infinitely long and a 2-dimensional mathematical model is adopted. According to the distributional approach, the problem is cast as the inversion of a linear integral operator acting on δ-distributions whose supports are representative of the scatterers' locations. The presence of a uniform grid of PEC (Perfect Electric Conductor) bars uniformly distributed around the investigation scene is shown to enhance the detection resolution when a single-frequency mono-static radar configuration is adopted. In this paper a numerical validation of this approach is presented.

Abstract
The problem of detecting and localizing 'thin' metallic scatterers from electromagnetic scattered field measurements is addressed. The scatterers are assumed to be infinitely long and a 2-dimensional mathematical model is adopted. According to the distributional approach, the problem is cast as the inversion of a linear integral operator acting on δ-distributions whose supports are representative of the scatterers' locations. The presence of a uniform grid of PEC (Perfect Electric Conductor) bars uniformly distributed around the investigation scene is shown to enhance the detection resolution when a single-frequency mono-static radar configuration is adopted. In this paper a numerical validation of this approach is presented.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
