The difference between partial coherence of an electromagnetic beam and its partial polarization state is a controversial issue that has again aroused interest  after some decades of relative consensus. Recently, and in the area of radar remote sensing, it has been the subject of study by the author of this paper in . In , this distinction, together with the analysis of the meaning of statistical independence of different scatterers in a SAR image, was used to examine the well-known polarimetric theory (PolSAR) developed by Cloude and Pottier. In the present work, we focus our attention on the consequences of this distinction for polarimetric SAR interferometry (PolInSAR).
