   Abstract : Millimeter-wave radar imaging has potential uses in applications such as material analysis and medical in-vivo scanning of tissue. This thesis is about measuring objects using a millimeter wave radar, implement radar imaging algorithms and evaluate the resulting images. READ MORE

3. 2. Experiment with Moving Target Focusing using GB-SAR

   University essay from Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandling

   Author : Krishna Mani Bajagain; [2014]
   Keywords : SAR; GB-SAR; GBP algorithm; Moving target Detection;

   Abstract : Ground Based Synthetic Aperture Radar (GB-SAR) refers to SAR system which is mounted on ground linear track. It works on same principle as conventional SAR. Nowadays GB-SAR plays prominent role in the studies of many natural phenomenon as well as in studying some artificial infrastructure or terrain. READ MORE

4. 3. Synthetic Aperture Radar Image Quality Measurements

   University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

   Author : Subrata Kumar Das; [2010]
   Keywords : Key Words: SAR; UWB SAR; spatial resolution; differential resolution; ISLR; PSLR; sinc function; IRF-SAR.;

   Abstract : Abstract Synthetic Aperture Radar (SAR) is an important tool for remote sensing now a day. SAR image quality measurements play an important role in the development of SAR image digital processing methods. The essential SAR image quality assessments are spatial resolutions, Integrated Sidelobe Ratio (ISLR) and Peak Sidelobe Ratio (PSLR). READ MORE

5. 4. 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

6. 5. 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
