The difference between partial coherence of an electromagnetic beam and its partial polarization state is a controversial issue that has again aroused interest [1] 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 [2]. In [2], 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).
