Interferometric Synthetic Aperture Radar (InSAR) technology has been widely used in various applications. The registration of SAR (Synthetic Aperture Radar) images is the first step in interferometric processing therefore accurate registration is essential for the successful creation and interpretation of interferometric products. However, with the growing number of SAR satellite launch and the...

Interferometric synthetic aperture radar (InSAR) is now routinely used to generate topographic data and to study geophysical phenomena, such as crustal deformation, ice motion and structure, and vegetation canopy depths [1]. In this study, we show that ionospheric disturbances can distort InSAR phase and correlation maps, and, further, that accurate image coregistration can compensate for ionos...

Interferometric Synthetic Aperture Radar (InSAR) is a new measurement technology, making use of the phase information contained in the Synthetic Aperture Radar (SAR) images. InSAR has been recognized as a potential tool for the generation of digital elevation models (DEMs) and the measurement of ground surface deformations. However, many critical factors affect the quality of InSAR data and lim...

Coherent Synthetic Aperture Radar (SAR) imagery and its potential in interferometric analysis widened the horizon of earth observation and geodetic measurements in the past decades. Overcoming the error sources in conventional Interferometric SAR (InSAR) techniques, the advanced methods of Persistent Scatterer Interferometry (PSI) and differential SAR Tomography (TomoSAR) have been able to retr...

Constellations of Synthetic Aperture Radar (SAR) satellites with short repeat time acquisitions allow exploration of active faults behavior with unprecedented temporal resolution. Along the North Anatolian Fault (NAF) in Turkey, an 80 km long section has been creeping at least since the 1944, Mw 7.3 earthquake near Ismetpasa, with a current Interferometric Synthetic Aperture Radar (InSAR)-deriv...

Within the last decade, Interferometric Synthetic Aperture Radar (INSAR) processing has emerged as an important extension of conventional SAR because it can be used to infer topographic heights of the imaged terrain. The demand for high-resolution, large coverage-area topographic data is driving new INSAR systems to acquire data in long strips. When processing long strips of INSAR data, the mot...

Interferometric synthetic aperture radar (InSAR) imaging is a recently developed geodetic technique capable of measuring ground-surface deformation with centimeter to subcentimeter vertical precision and spatial resolution of tens-of-meter over a relatively large region (~10 km). The spatial distribution of surface deformation data, derived from InSAR images, enables the construction of detaile...

8 9 10 A Synthetic Aperture Radar (SAR) is an active sensor transmitting pulses of polarized 11 electromagnetic waves and receiving the backscattered radiation. SAR sensors at different 12 wavelengths and with different polarimetric capabilities are being used in remote sensing of 13 the Earth. The value of an analysis of backscattered energy alone is limited due to ambiguities 14 in the possib...

An accurate digital elevation model (DEM) is a critical data set for characterizing the natural landscape, monitoring natural hazards, and georeferencing satellite imagery. The ideal interferometric synthetic aperture radar (InSAR) configuration for DEM production is a single-pass two-antenna system. Repeat-pass single-antenna satellite InSAR imagery, however, also can be used to produce useful...

Interferometric synthetic aperture radar (InSAR) observations of ice-shelf flow contain ocean-tide and atmospheric-pressure signals. A model-based correction can be applied, but this method is limited by its dependency upon model accuracy, which in remote regions can be uncertain. Here we describe a method to determine two-dimensional ice-shelf flow vectors independently of model predictions of...
