Polarimetric calibration accuracy is a key factor in the quantitative use of polarimetric SAR data as well as the design of future SAR system. This paper presents an approach to determine the maximum acceptable distortion level remaining after polarimetric calibration in Polarimetric SAR Interferometry (Pol-InSAR). PolInSAR distortion model of calibration is reviewed and discussed firstly. Then...

A new interferometric SAR (InSAR) procedure for DEM generation was employed to generate different DEMs from ERS SAR image pairs. The procedure was validated comparing the InSAR DEMs with a suited reference DEM. In the first part of the paper the principal features of the procedure are briefly summarised. The second part is focused on the quality assessment of the InSAR DEMs. They cover the same...

Modern airborne SAR sensors provide spatial resolution in the order well below half a meter. In such data many features of urban objects are visible, which were beyond the scope of radar remote sensing only a few years ago. Core elements of urban infrastructure are bridges. In high-resolution InSAR data even small bridges are mapped to extended data regions covering large numbers of pixels. The...

Interferometric synthetic aperture radar (InSAR) is a powerful geodetic tool used to construct digital elevation models of the earth’s topography and to image centimeter-scale displacements associated with crustal deformation and the flow of ice sheets. The past decade has seen significant improvements in our understanding of earthquakes, volcanoes, and glaciers as a direct result of this techn...

Multiple-antennaSAR interferometryinvolves the use of three or more antennas to reduce the overall phase ambiguities and phase noise in interferometric data. This paper presents a Bayesian approach to topographic mapping with multiple-antenna SAR interferometry. Topographic reconstruction is formulated as a parameter estimation problem in the model-based Bayesian inference framework. An InSAR s...

A new synthetic aperture radar interferometry (InSAR) data processing method comprehensively based on three parts of complex images is introduced. The method includes image pair registration and interferogram creation. These methods are improved and extended, and a set of integrated technology, which is named contoured correlation interferometry (CCI), is formed for the InSAR data processing. T...

SAR image coregistration is a key procedure before starting InSAR time-series analysis. In this paper, we present a strategy to coregister SAR image subsets, instead of single SAR images, in attempt to improve InSAR time-series analysis. First, all potentially coherent image pairs are coregistered and divided into several image subsets, depending on a coregistration quality index or baseline in...

In this paper, a new function model for determining the minimum and maximum detectable deformation gradient in synthetic aperture radar interferometry (InSAR) with Envisat ASAR images is developed. The model incorporates the parameters of both interferometric coherence and multilook operator for 1, 5 and 20, rather than the interferometric coherence only in previous studies. Experimental result...

Differential synthetic aperture radar interferometry (D-InSAR), is a remote sensing technique that could measure earth surface deformation and has gained extensive use along with its development as a technique and subject, from classical to advanced DInSAR. The main principles of both were concisely depicted and the differences and relations between highlighted. Then an introductive review conc...

The levee system in California’s Sacramento–San Joaquin Delta helps protect freshwater quality in a critical estuarine ecosystem that hosts substantial agricultural infrastructure and a large human population. We use space-based synthetic aperture radar interferometry (InSAR) to provide synoptic vertical land motion measurements of the Delta and levee system from 1995 to 2000. We find that Delt...
