POLINSAR - Polarimetric SAR Interferometry

Context and objectives

In polarimetric SAR interferometry (PolInSAR), polarimetric techniques are introduced into SAR interferometry applications to provide combined sensitivity to the vertical distribution of scattering mechanisms. As a result, it becomes possible to investigate the three-dimensional structure of vegetation cover using a single-frequency polarimetric SAR. The topics to be covered in this three-year project include : (1) PolInSAR processing; (2) PolInSAR physics; (3) PolInSAR fusion; (4) PolInSAR potentialities in remote sensing.

Project outcome

Expected scientific results

  • The PolInSAR processor has been developed and validated by CSL, taking (and often helping to develop) the ESA PolSARpro software as reference (see appended images for illustration).
  • The PolInSAR radiative transfer model has been developed. Interaction with the outputs of the CSL PolInSAR processor is in progress.
  • A brainstorming on PolInSAR potentialities for remote sensing, gathering the Consortium and the User Members of the Steering Committee, is planned for September 2006.
