The influence of the subsurface properties of ice sheets on polarimetric synthetic aperture radar interferometry (Pol-InSAR) measurements is well known. In order to invert this relationship for the extraction of geophysical parameters from Pol-InSAR data, models of the subsurface scattering structure are required. One potential application is the estimation of the penetration bias in interferometric surface elevation measurements of ice sheets, which was demonstrated based on single-baseline data. However, the model complexity and performance are constrained by the limited observation space. This study, therefore, investigates the inversion of subsurface scattering structures with multi-baseline fully polarimetric Pol-InSAR data, which allows accounting for more realistic scattering scenarios. Preliminary results indicate a more robust inversion of the penetration bias compared to the single-baseline case.
