Abstract

A customized imaging procedure is presented and tested in order to considerably improve the accuracy of reconstruction of unknown buried targets using Ground Penetrating Radar (GPR) systems for a variety of NDT (nondestructive testing) applications. A 'synthetic setup' is implemented by means of a numerical tool, which can take into account the distinctive features of the antenna system and of the signals used for the actual GPR illumination. Precise computation for both the incident and the backscattered field distributions is thus achieved in the investigated GPR scenarios. By suitable data processing, an enhanced solution of the inverse problem is reached. Challenging examples of imaging for buried dielectric targets illustrate the improvements achieved through this technique compared to standard approaches, in terms of definition and resolution.
