Airborne polarimetric SAR interferometry

IGARSS '98. Sensing and Managing the Environment. 1998 IEEE International Geoscience and Remote Sensing. Symposium Proceedings. (Cat. No.98CH36174), 1998
The authors show for first time the applicability of polarimetric interferometry techniques on high resolution interferometric scattering matrix airborne data. They point out the main requirements considering system hardware as well as data processing and calibration algorithms which are important for the polarimetric interferometric data evaluation ...

Backprojection SAR interferometry

International Journal of Remote Sensing, 2015
Synthetic aperture radar SAR interferometry uses the phase difference between two SAR antennas to obtain an elevation estimate of the imaged terrain. Using an initial digital elevation model DEM, the time-domain backprojection algorithm implicitly removes the terrain height phase from images during image formation.

Polarimetric SAR interferometry

IEEE Transactions on Geoscience and Remote Sensing, 1998
The authors examine the role of polarimetry in synthetic aperture radar (SAR) interferometry. They first propose a general formulation for vector wave interferometry that includes conventional scalar interferometry as a special case. Then, they show how polarimetric basis transformations can be introduced into SAR interferometry and applied to form ...

Permanent scatterers in SAR interferometry

IEEE 1999 International Geoscience and Remote Sensing Symposium. IGARSS'99 (Cat. No.99CH36293), 2001
Differential SAR interferometry (DInSAR) is an unique tool for low-cost, large-coverage surface deformations monitoring. As well known, the technique involves interferometric phase comparison of SAR images gathered at different times and has the potential to provide millimetric accuracy.

X-SAR interferometry: first results

IEEE Transactions on Geoscience and Remote Sensing, 1995
Repeat-pass interferometry data were acquired during the first and second SIR-C/X-SAR missions in April and October 1994. This paper presents the first results from X-SAR interferometry at four different sites. The temporal separations were one day and six months.

Maximum likelihood array SAR interferometry

1996 IEEE Digital Signal Processing Workshop Proceedings, 2002
Conventional SAR interferometers derive the surface height from an estimate of the phase difference between the SAR processed echoes received by two displaced phase centers. This paper introduces a maximum likelihood algorithm to process the SAR data from an array of K phase centers.

Sar Interferometry And Its Applications

Surveys in Geophysics, 2000
Satellite mounted Synthetic Aperture Radars (SAR) provide informationof the amplitude of the backscatterer its phase. This corresponds to the totaltravel time (source receiver and back), plus the phase of the scatterer itself.SAR interferometry yields the image of the differences of the phases takenin two successive passes.

Single-baseline polarimetric SAR interferometry

IEEE Transactions on Geoscience and Remote Sensing, 2001
Examines the application of single-baseline polarimetric SAR interferometry to the remote sensing and measurement of structure over forested terrain. For this, a polarimetric coherent scattering model for vegetation cover suitable for the estimation of forest parameters from interferometric observables is introduced, discussed and validated.
