Subsurface and Through-the-Wall Imaging

In the last half-century, probing matter with electromagnetic (EM) fields to give a human-intelligible image of a region under test in a non-invasive fashion has been a very attractive field of research. Notwithstanding, the processing of data collected – for instance – by means of a ground penetrating radar (GPR) is still considered a
challenging problem. In this context, innovative imaging techniques have been developed by the members of the ELEDIA Research Center network to provide easy-to-interpret and reliable images of subsurface and/or through-the-wall domains. The application scenarios considered within ELEDIA include

  • Unexploded ordnances detection;
  • Archaeology;
  • Civil engineering;
  • Geosciences;
  • Structural health monitoring
  • Forensic investigations;
  • Search and rescue missions;
  • Surveillance, reconnaissance, and security.

The methodologies developed within ELEDIA are based on a wide variety of paradigms, including (i) the real-time detection and classification of buried objects based on the learning-by-example (LBE) techniques, (ii) the use of deterministic, stochastic, and probabilistic compressive sensing (CS) strategies combined with multi-resolution and multi-frequency schemes to provide robust and accurate quantitative reconstructions of the inaccessible investigated domain.
