On The Role of Coherence Optimization in Polarimetric SAR Interferometry

The quality of an interferogram of two SAR images is measured by a concept called coherence. Coherence is inversely proportional to the interferogram phase variance. Since the interferogram phase is sensitive to the terrain topography, coherence maximization has a potential application in DEM generation. In this paper, the interferometric coherence optimization methods are reviewed. The problem...

Persistent Scatterer Pairs (psp) Approach in Very High Resolution Sar Interferometry

Terrasar-x High Resolution Spotlight Persistent Scatterer Interferometry

The new class of meter-resolution spaceborne SAR systems (TerraSAR-X and COSMO-Skymed) offers a tremendous improvement in interferometric monitoring of urban areas and man-made infrastructure. The high resolution fits well to the inherent scale of buildings (floor height, distance of windows, etc.). In particular, Persistent Scatterer Interferometry (PSI) benefits substantially from this new da...

Indoor experiments on polarimetric SAR interferometry

A coherence optimization method, which makes use of polarimetry to enhance the quality of SAR interferograms, has been experimentally tested under laboratory conditions in an anechoic chamber. By carefully selecting the polarization in both images, the resulting interferogram exhibits an improved coherence above the standard HH or VV channel. This higher coherence produces a lower phase varianc...
