The Group

Radar Remote Sensing with Synthetic Aperture Radar (SAR)

SAR Polarimetry:

• Exploration of the fully polarimetric scattering behaviour of an illuminated scene
• Calibration of ground based systems
• Development of inversion models and algorithms for the estimation of bio- and geophysical parameters from polarimetric SAR data

SAR Intereferometry (Differential SAR and Single-Pass Interferometric SAR, TomoSAR)

• Monitoring and analysis of sufrace deformation in the wake of natural geophysical processes and anthropogenic activities, using differential intereferometry / persistent scatterer interferometry (PSI)
  
• Developing tomographic techniques for 3D retrieval of surface reflectivity in urban and alpine regions for coherent scatterers
  
• Understanding snow metamorphism using co-polar phase differences
  
• Development of methods to estimate biomass and soil moisture signal

Polarimetric SAR Interferometry

• Inversion methodology development and validation for the estimation of bio- and geophysical parameter from multi-parameter (i.e. multi-frequency, -baseline, -temporal) Pol-InSAR data.

Terrestrial radar remote sensing

We are equipped with a ground-based radar interferometer. It is a Ku band real aperture FMCW radar. This is of interest for terrain mapping (generation of DEMs), deformation measurement and agricultural applications.
