1. 1. Feasibility study of dam deformation monitoring in northern Sweden using Sentinel1 SAR interferometry

   Magister-uppsats, Högskolan i Gävle/Samhällsbyggnad, GIS

   Författare :Cecilia Borghero; [2018]
   Nyckelord :SAR interferometry; Sentinel-1A; dam deformation monitoring;

   Sammanfattning : Dams are man-made structures that in order to keep functioning and to be considered structurally healthy need constant monitoring. Assessing the deformation of dams can be time consuming and economically costly. LÄS MER

3. 2. Differential Interferometry and Multiple-Aperture Interferometry for Retrieving Three-Dimensional Measurements of Glacial Surface Velocity

   Master-uppsats, Stockholms universitet/Institutionen för naturgeografi

   Författare :Luke Webber; [2016]
   Nyckelord :Differential Interferometry; Multiple-Aperture Interferometry; 3D; Glacial Surface Velocity;

   Sammanfattning : The measurement and monitoring of glacial surface velocity is important for many aspects of glaciology, such as determining the mass balance, for characterising the stability or instability of glaciers, or the identification of potential hazards from surging glaciers or Jökulhlaups, a type of glacial outburst flood. Predominately measurements of glacial surface velocity have been produced using either differential interferometry (DInSAR) applied to radar data, or offset-tracking applied to either optical or radar data.

4. 3. Monitoring of Santorini (Greece) volcano during post-unrest period (2014-2016) with Interferometric Time series of Sentinel-1A

   Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Författare :Christos Bountzouklis; [2016]
   Nyckelord :Santorini Volcanic Complex; earth observation; volcanic hazard; SAR Interferometry; Sentinel-1A; physical geography and ecosystem science; Earth and Environmental Sciences;

   Sammanfattning : Ground deformation monitoring is one of the main geoindicators that should be considered to assess volcanic hazard. Satellite earth observation data and Synthetic Aperture Radar (SAR) interferometry have been used continuously since 1992 to measure or study the temporal evolution of surface deformation in volcanic areas in conjunction with ground-based geodetic measurements.

5. 4. Development of a GB-SAR System and Perform Basic and Advance Measurements for a Fixed Target

   Master-uppsats, Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

   Författare :Mohammed Faisal; [2011]
   Nyckelord :Double Ridge Guide Horn Antenna; Global Backprojection GBP ; Ground-Based SAR GB-SAR ; Interferometry; Low loss-high frequency cable; Vector Network Analyzer VNA .;

   Sammanfattning : Ground-Based Synthetic Aperture Radar (GB-SAR) system is a new innovative monitoring technique has been invented depending on the use of ground based applications and highly repeatable measurements. GB-SAR is a new class of SAR system based on unconventional platform like ground, building and ground vehicles that acts as a useful complement of airborne and spaceborne SAR system. LÄS MER

7. 5. Ground-Based Synthetic Aperture Radar Data processing for Deformation Measurement

   Master-uppsats, KTH/Geodesi och satellitpositionering

   Författare :Andreas Jungner; [2009]
   Nyckelord :;

   Sammanfattning : This thesis describes a first hands-on experience working with a Ground-Based Synthetic Aperture Radar (GB-SAR) at the Institute of Geomatics in Castelldefels (Barcelona, Spain), used to exploit radar interferometry usually employed on space borne platforms. We describe the key concepts of a GB-SAR as well as the data processing procedure to obtain deformation measurements. LÄS MER
