1. 16. Ground-Based Synthetic Aperture Radar Data processing for Deformation Measurement

   University essay from KTH/Geodesi och satellitpositionering

   Author : Andreas Jungner; [2009]
   Keywords : ;

   Abstract : 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. READ MORE

3. 17. Study of the Local Backprojection Algorithm for Image Formation in Ultra Wideband Synthetic Aperture Radar

   University essay from Blekinge Tekniska Högskola/Avdelningen för telekommunikationssystem

   Author : Ishtiaque Ahmed; [2008]
   Keywords : SAR; LBP; UWB; Subimage; Subaperture; Image formation; Backprojection;

   Abstract : The purpose of this thesis project is to study and evaluate a UWB Synthetic Aperture Radar (SAR) data image formation algorithm, that was previously less familiar and, that has recently got much attention in this field. Certain properties of it made it acquire a status in radar signal processing branch. READ MORE

4. 18. Enhanced SAR Image Processing Using A Heterogeneous Multiprocessor

   University essay from Institutionen för datavetenskap

   Author : YU SHI; [2008]
   Keywords : CELL Broadband Engine; Synthetic antenna aperture; Fast Factorized Back Projection FFBP algorithm; C language; parallel programming; parallel computing; Matlab;

   Abstract : Synthetic antenna aperture (SAR) is a pulses focusing airborne radar which can achieve high resolution radar image. A number of image process algorithms have been developed for this kind of radar, but the calculation burden is still heavy. So the image processing of SAR is normally performed “off-line”. READ MORE

5. 19. A Study of Fast Backprojection Algorithm for UWB SAR and a Comparison between Fast- and Global Backprojection

   University essay from Blekinge Tekniska Högskola/Avdelningen för signalbehandling

   Author : Hawa Yves; [2008]
   Keywords : Synthetic Aperture Radar; Ultra Wide-band; time-domain algorithms; Global Backprojection; Fast Backprojection; SAR image processing; interpolation techniques.;

   Abstract : In this thesis, we present a study of the Fast Backprojection (FBP) known to be a fast time-domain algorithm for image retrieval in Synthetic Aperture Radar (SAR). As a time domain algorithm, FBP possesses inherent advantages such as perfect motion compensation, unlimited scene size, wide bandwidth and ability to handle long integration angles. READ MORE

6. 20. Processing SAR data using RangeDoppler and Chirp Scaling Algorithms

   University essay from KTH/Geodesi och satellitpositionering

   Author : Naeim Dastgir; [2007]
   Keywords : ;

   Abstract : Applications of self-illuminating remote sensing systems, and among those, Radar Imagery is growingrapidly. Unique properties of Synthetic Aperture Radar (SAR) system makes it one of the most popularand applicable methods of self illuminating remote sensing techniques for ground deformationmonitoring, seismic studies, and many photogrammetry applications.
