“…Amongst the other geophysical investigation methods [1,[3][4][5], ground penetrating radar (GPR) appears to be a promising candidate, as it allows non-invasive, cost-effective, flexible surveys to be undertaken. In fact, several examples of its application to the detection and monitoring of buried pipelines can be found in the literature [6][7][8][9][10][11][12].…”

“…The approach takes advantage of the assumed knowledge of the monitored scenario by exploiting in the model the location, size and electric characteristics of the pipeline. This approach has been already applied to a single-fold/multi-receiver GPR configuration [11]; here, we consider the conventional multibistatic configuration usually exploited in utility surveys. As the other main topic of the work, we discuss about the choice of the regularization parameter in the inversion.…”

“…As the other main topic of the work, we discuss about the choice of the regularization parameter in the inversion. While in [11] the regularization parameter needed in the inversion was determined only by taking into account the expected noise level, here we also constrain it to the features of the scenario. The reconstruction performances of the tomographic algorithm are assessed against synthetic data generated by a finitedifference time-domain (FDTD) forward modeling scheme that is able to simulate realistic GPR experiments [20,21].…”

Abstract-In this work, we present an inverse scattering approach to address the timely detection of damage and leakage from pipelines via multi-bistatic ground penetrating radar (GPR) surveys. The approach belongs to the class of linearized distorted wave models and explicitly accounts for the available knowledge on the investigated scenario in terms of pipe position and size. The inversion is regularized by studying the properties of the relevant linear operator in such a way to guarantee an early warning capability. The approach has been tested by means of synthetic data generated via a finite-difference timedomain forward solver capable of accurately and realistically modeling GPR experiments. The achieved results show that it is possible to detect the presence of leakage even in its first stages of development.

“…In order to improve the interpretability of GPR data, inverse scattering and migration algorithms [3][4][5][6][7][8], including microwave tomography (MT) techniques [9][10][11], have also been used in different scenarios related to GPR surveys. MT has been successfully used, for example, to investigate water leakage from a large metallic pipe in [12], where it was able to give more reliable information than a direct radargram analysis. In addition, several GPR surveys at different time intervals were done for a controlled oil spill and analysed through MT in [13].…”

This paper provides a comparative study between microwave tomography and synthetic time-reversal imaging techniques as applied to ground penetrating radar (GPR) surveys. The comparison is carried out by processing experimental data collected at a controlled test site, with different types of buried targets at given subsurface depths and representative soil conditions. It is shown that the two techniques allow us to obtain complementary information about position, depth and size of the targets from a single GPR survey.
