Multiple transducer synthetic aperture sonar interferometry for emulating SAR interferometry
… transducer single-pass synthetic aperture sonar interferometry in air is a technique that can emulate topographic mapping techniques that have not been implemented using radar or that are relatively expensive and difficult to obtain in practice for the radar engineer who wishes to test algorithms …

Three applications of satellite borne repeat pass SAR interferometry in Southern Africa
Synthetic Aperture Rada Interferometry (InSAR) is a relatively new remote sensing technique, which can be used to derive precise topographic height change information over large areas. It is a technique which has been used in a great variety of situations, from the topographic mapping of Venus to …

Ground deformation observed in the western Corinth rift (Greece) by means of SAR interferometry
… have been (and are) performed. Moreover dense SAR data are available since 1992 and the ERS1 mission. Motivated by the lack of precise and extended mapping of the vertical deformation of the area and by the limitations of the GPS network (in terms of density of points) we investigate, model and …

SAR interferometry analysis of surface processes in the Pamir – Tien Shan active orogens - emphasis on coseismic deformation and landslides
This thesis presents new approaches of SAR methods and their application to tectonically active systems and related surface deformation. With 3 publications two case studies are presented: (1) The coseismic deformation related to the Nura earthquake (5th October 2008, magnitude Mw 6.6) at the …

Implementation and analysis of a bayesian approach to topographic reconstruction with multiple antenna synthetic aperture radar interferometry
Multiple-antenna synthetic aperture radar (SAR) interferometry is a single-pass interferometry technique for topographic mapping. A Bayesian model-base approach to topographic recontruction with multiple-antenna SAR interferomety, proposed by Dr. A. J. Wilkinson, is implemented and analysed in this …

Characteristics of active deformation, fault interaction, and earthquake triggering in a rapidly-deforming complex normal fault network (south-west Türkiye)
… cycle. In this thesis, Coulomb stress modelling, SAR interferometry, and field work are combined with a comprehensive literature review to study active deformation, fault interactions, and earthquake triggering mechanisms in complex normal fault networks, with the Western Anatolian Extensional …

Advancements in Satellite SAR Methods for Monitoring Civil Infrastructure
Synthetic Aperture Radar (SAR) imaging enables large-scale, remote monitoring of civil infrastructure. SAR allows for monitoring without installation or maintenance, unlike traditional contact-type sensors. Whilst SAR interferometry (InSAR) is widely used for land monitoring, its application to …

Atmospheric water vapour tomography for DInSAR application and effect of volcanic plume on the microwaves
A particular synergy among GPS and SAR techniques, to improve the precision of the current ground deformation monitoring techniques,is investigated. The study of atmospheric anomalies in the GPS EM waves propagation is useful to extrapolate information about the wet refractivity ?eld. Because of …

Untersuchungen zu gezeitenbedingten Höhenänderungen des subglazialen Lake Vostok, Antarktika
… mit ganz- und halbtägigen Perioden. Die SAR-Interferometrie als flächenhaft arbeitende Methode zur Bestimmung von Höhenänderungen lässt den räumlichen Verlauf der Deformation erkennen. Dabei zeigt sich, dass sich die Aufsetzzone auf dem etwa 50 km breiten See bis in die Seemitte ersteckt. …
