Abstract:
|
In this paper, the potentials of polarimetric coherenceoptimization
techniques for differential interferometric SAR
(DInSAR) applications are examined. For this purpose, the
cutting-edge approaches available in the literature are
considered. First, synthetic PolSAR data simulating
homogeneous distributed scatterers are employed to demonstrate
the convergence of the optimized differential phase to the
deformation phase information. Then, real X-band ground-based
PolSAR acquisitions concerning an urban environment are
analyzed. The relation between optimum coherences and
corresponding optimum phase in terms of deformation on
retrieval is carefully analyzed using two zero-baseline fullypolarimetric
data sets. In the end, general conclusions about the
advantages and drawbacks of the alternative maximization
approaches are drawn. |
