Abstract:
|
In this paper, the study of polarimetric optimization
techniques for Differential SAR Interferometry (DInSAR)
applications is analyzed. This work has been carried out in
the framework of deformation map retrieval on landslides.
A large number of landslides occur on vegetated areas with
a poor density of temporal coherent scatterers, which are
characterized by a fast decorrelation at X-band. The
objective of the techniques proposed in this paper is to
increase the number of temporal coherent scatterers to
improve the robustness of the DInSAR algorithms
exploiting the polarimetric capabilities of data. The
relationship between optimum coherences and its
corresponding phase quality in terms of DInSAR
application is analyzed using Ground-Based SAR zerobaseline
fully-polarimetric data. |
