Synthetic Aperture Radar (SAR)

  • Analysis and modelling of HR and VHR SAR signals
  • Building detection and 3D reconstruction in VHR SAR images
  • Change detection (2D and 3D)
  • Automatic classification
  • Analysis of temporal series of HR and VHR SAR images.

Ground Penetrating Radar and Radar Sounder

  • Statistical analysis and characterization of radar sounder signals
  • Pre-processing techniques (clutter estimation and noise reduction, filtering, etc.)
  • Feature extraction and automatic classification of subsurface layers or patterns
  • Design of radar sounding instruments for planetary exploration

Radar sounder data of the subsurface of the North Pole of Mars acquired by the SHARAD instrument, and examples of possible elaborations:
(top right) automatic detection of basal returns aimed at the estimation of ice thickness and basal topography;
(bottom left) automatic detection of surface clutter returns on radargrams through clutter simulation and matching with real data;
(bottom right) automatic detection and characterization of subsurface linear features aimed at the mapping of icy layers.
