On the modeling of the bistatic coherent scattering from a rough surface
In this contribution, we investigate on the coherent bistatic scattering generated by a radar system when illuminating a rough surface. Moving from the well-known scattering theory based on the Kirchhoff approximation, we propose an extended formulation of the Fung-Eom model, by introducing a higherorder expansion on the phase term of the impinging spherical wave. We demonstrate and discuss the importance of such correction for the accurate characterization of the coherent scattering generated in bistatic radar system. We give insight, for the first time, on the role played by both the antenna pattern and the wavefront sphericity in bistatic scattering in the whole incidence plane, not limiting the analysis to the backscattering and specular directions. This is particularly important for practical applications, such as the modeling of the scattering generated by sources of opportunity

Performance of free-space tomographic imaging approximation for shallow-buried target detection
Forward-looking ground penetrating radar (FL-GPR) is an emerging modality that permits standoff sensing of targets buried at shallow depths in the ground. Most FL-GPR imagery is obtained using free-space approximation, neglecting the presence of the air-to-ground interface and assuming the propagation as occurring in a homogeneous dielectric medium. In this paper, we compare the performance of the approximate free-space tomographic imaging with that of a tomographic algorithm which accounts for the presence of the actual halfspace geometry. The half-space approach implements the spectral representation of the dyadic Green's function. Using numerical electromagnetic FL-GPR data, we investigate the impact of the free-space approximation on the image quality as well on the image-domain statistics of the targets and rough surface clutter
A customized numerical procedure for accurate target reconstruction through GPR surveys
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
La tutela giurisdizionale tra diritto dell’Unione europea e diritto nazionale
Il presente scritto esamina la specificità dell’ordinamento dell’Unione facendo riferimento i principi dell’efficacia diretta e del primato e la tutela dei diritti dei privati. Nell'affrontare il tema della tutela giurisdizionale si fa riferimento alla cooperazione tra giudici nazionali e Corte di giustizia e alla competenza pregiudiziale dedicando specifica attenzione ai rapporti tra Corte costituzionale italiana e Corte di giustizia
Bistatic coherent scattering from rough soils with application to GNSS reflectometry
We present and discuss an electromagnetic model for the description of the coherent scattering from bare soils illuminated by a radar system under arbitrary bistatic geometries. The scattering problem is solved under the Kirchhoff approximation (KA) accounting for both the sphericity of the wavefront of the incident wave and the radiation pattern of the transmitting and receiving antennas. We propose here a general formulation and solution of the scattering problem applicable to an arbitrary bistatic geometry. We discuss and demonstrate the importance of our extension for the characterization of the coherent scattering generated in bistatic radar systems, both inside and outside the plane of incidence. The model is validated against the numerical solution of the Kirchhoff integral and, in the case of the perfect plane conductor, by comparison with the image theory. The work is intended to provide a simple methodology to characterize the coherent normalized radar cross section (NRCS) of a rough surface to be used within the radar equation for extended targets, similarly to what is done for the incoherent component. It aims at enabling a local characterization of the coherent scattering in realistic conditions (e.g., in the presence of inhomogeneous and mountainous surfaces), a feature that is particularly important for practical applications, such as the modeling and understanding of the bistatic scattering generated by sources of opportunity and specifically for Global Navigation Satellite System Reflectometry (GNSS-R) related applications
Multi-aperture processing for improved target detection in forward-looking GPR applications
An advanced imaging procedure that exploits the intrinsic multi-aperture nature of a ground-based forward-looking GPR is presented. The imaging algorithm takes into account the near-field nature of the sensing configuration. Numerical data based on electromagnetic modeling of shallow buried targets in ground with a rough-surface profile are used in conjunction with a likelihood ratio test detector to demonstrate the effectiveness of the proposed approach
