This paper gives an overview of recent progress in radar polarimetry and radar polarimetric interferometry. Both techniques are of special importance for the inversion of physical scatterer parameters from radar remote sensing data. A unified treatment of polarisation effects in radar polarimetry and polarimetric interferometry based on eigenvalue processing is addressed providing a link between signal processing techniques and coherent electromagnetic models for random media scattering. In this context, the main applications of polarimetry in radar remote sensing such as single and multi-frequency polarimetric classification, the estimation of surface roughness and moisture content and vegetation structure estimation are reviewed.
