Interferometric coherence optimization using the polarimetric signatures
نویسندگان
چکیده
The coherence optimization based on the eigenvalues in radar polarimetry is used to enhance the quality of SAR interferograms. A second and an alternative coherence optimization algorithm which consists in looking at the possible coherence for every combination of elliptical polarizations extracted from the polarimetric signatures and selecting the highest one is also developed, tested and compared with the coherence optimization method. It is shown that, the coherence algorithm based on polarimetric signature performs better than the 1 approach but it takes a longer execution time. SAR images used have been acquired at Pband over the forest of Tapajos in Brazil. Keywords-component; interferometry; polarimetry; optimization;interferogram

Land Cover Classification based on Polarimetric Coherence Signatures
The paper presents a new form of polarimetric interferometric information visualization: polarimetric coherence signatures. These signatures combine the idea of conventional polarization signatures and the concept of interferometric coherence. The polarimetric coherence signature plot shows the magnitude of the interferometric coherence as a function of the polarization ellipse parameters (elli...

SAR polarimetry makes use of the polarization dependent scattering response of each pixel within the imaged area. The polarimetric response is highly sensitive to the scattering mechanism of a pixel. SAR interferometry is sensitive to the location of a pixel and its scattering geometry. The location of a pixel can be measured by the phase difference between two coherent SAR images using SAR int...

This Lecture mainly based on [1, 2] presents the role of Polarimetry in SAR Interferometry. A general formulation for vector wave interferometry is presented that includes conventional scalar interferometry presented in the respective former lecture as a special case. Based on this formulation, the coherence optimization problem can be solved to obtain the optimum scattering mechanisms that lea...
متن کاملOn 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...

Synthetic Aperture Radar (SAR) data is extensively used in recent decades for Earth surface monitoring. Advantages of SAR are well-known: good resolution, all-weather, day-and-night etc. SAR Interferometry (INSAR) is a well-established technique which has a lot of applications, e.g., topography mapping, change detection, estimation of surface displacements, thematic mapping. Repeat-pass interfe...
