Ice and Snow

The understanding and development of Pol-InSAR applications with respect to ice and snow is today in a early stage. First E-SAR airborne campaigns provided appropriate data sets initiating data analysis and leading to first insights and early results.

  • A multibaseline Pol-InSAR experiment in the Austrian Alps demonstrated that snow acts as a volume scatterer (even at L-band) and a strong dependency of the interferometric coherence on polarization – due to the strong underlying ground scattering component and similar to the agriculture vegetation case.
  • In 2005 the SVALEX multi-frequency / multibaseline Pol-InSAR experiment has been flown in Svalbard, Norway supported by ground measurements.
