Single-baseline polarimetric SAR interferometry
IEEE Transactions on Geoscience and Remote Sensing, 2001Examines 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.

Backprojection SAR interferometry
International Journal of Remote Sensing, 2015Synthetic 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.

Efficient Interpolation of SAR Images for Coregistration in SAR Interferometry
IEEE Geoscience and Remote Sensing Letters, 2007An efficient polynomial interpolation method is proposed to reduce the computational burden of the coregistration of synthetic aperture radar images in interferometric processing. The method can be viewed as an application of the Farrow interpolator technique and requires a series of 2-D fast Fourier transforms (FFTs).

Multibaseline post-processing for sar interferometry
Processing Workshop Proceedings, 2004 Sensor Array and Multichannel Signal, 2005In this paper we provide a tutorial description of recent results of the research activity at the University of Pisa on multibaseline (MB) InSAR processing. The main focus is on the problem of retrieving both heights and radar reflectivities of natural layover areas by means of a cross-track InSAR (XTI-SAR) system.

Landuse mapping with ERS SAR interferometry
IEEE Transactions on Geoscience and Remote Sensing, 2000Two landuse maps and a forest map of three different areas in Europe were completed with ERS SAR interferometry. The test sites represent various geomorphological regions with different cover types. In this article, the mapping algorithms are presented, the results are summarized, and the potential and limitations of ERS SAR interferometry for landuse ...

Retrieval of vegetation parameters with SAR interferometry
IEEE Transactions on Geoscience and Remote Sensing, 1997The potential of SAR interferometric techniques for the retrieval of vegetation parameters was investigated using ERS-1 data over agricultural and forested test sites. In a first experiment an interferometrically derived forest map was generated. The classification was based on the interferometric correlation and the backscatter intensities. The result

Stable Coherent Area in SAR interferometry
2009 IEEE International Geoscience and Remote Sensing Symposium, 2009Synthetic aperture radar images have been a tool of interest in many land cover studies for their night and day, all weather conditions operability. The classic InSAR technique is often limited by temporal and geometrical decorrelation, especially in the context of long time series analysis.

Approximation Eerror in Differential SAR Interferometry
IGARSS 2008 - 2008 IEEE International Geoscience and Remote Sensing Symposium, 2008Two approximations are used in "Three-pass" D-InSAR (Differential SAR Interferometry). First, in this paper, the error caused by the approximations is deduced and defined as First-order Approximation Error. Then, the characteristics of First-order Approximation Error are discussed in theory and proved by two experiments.

Layover solution in multibaseline SAR interferometry
IEEE Transactions on Aerospace and Electronic Systems, 2002In this work, spectral estimation techniques are used to exploit baseline diversity of a multichannel interferometric synthetic aperture radar (SAR) system and overcome the layover problem. This problem arises when different height contributions collapse in the same range-azimuth resolution cell, due to the presence of strong terrain slopes or ...
