The development of radar polarimetry and radar interferometry is advancing rapid ly. With radar polarimetry, the textural fine-structure, target orientation, sy stemmetries and material constituents can be recovered with considerable improve ment above that of standard amplitude-only radar; with radar interferomety, the elevation structure of a target can be explored. In Polarimetric Synthetic Aper ture Radar Interferometry (Pol-InSAR) imaging, it is possible to recover such c o-registered textural and spatial information from Pol-InSAR data sets simultan eously. Pol-InSAR technique significantly improves the performance of conventio nal scalar radar interferometry by introducing radar polarimetry technique into SAR interferometry. Polarimetric SAR interferometry generates different interfer ograms of the same scene. Each interferogram is associated with a particular sca ttering mechanism. The interferometric analysis of a full coherent polarimetric data set enables the combination of the final structure properties and the spati al information of the target. Polarimetric Synthetic Aperture Radar Interferomet ry is a potential technique, which not only allows a more sophisticated physical interpretation of scattering mechanism but also improves the accuracy of the in terferometric measurements. In this paper we introduce the development of this t echnique and its basic principles, and then discuss some key problems that must be solved. Finally, we present the applications and developing tendency of Pol- InSAR technique.
