  1. 11. Fast Back Projection Algorithm for Bi-Static SAR Using Polar Coordinates

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Omer Elhag; [2012]
    Keywords : Bi-static SAR; Fast Backprojection; Global Backprojection; monostatic SAR; SAR image processing; Synthetic Aperture Radar; time domain algorithms; Ultra Wide-beam; UWB Bistatic SAR.;

    Abstract : Synthetic Aperture Radar (SAR) plays a significant role in geophysical studies and remote sensing applications. SAR inherits the benefits of imaging RADAR over the other optical sensors such as working in all weather conditions and working independently of sunlight. READ MORE

  3. 12. Fixed Receiver Bi-Static SAR Image Formation Using C/A code and Global Back-Projection Algorithm

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Ahmed Hamza Ibrahim Makki; [2010]
    Keywords : Bi-static SAR; monostatic SAR; GBP; C A code.;

    Abstract : Synthetic Aperture Radar (SAR) is used to generate a high resolution radar image from low resolution aperture data. Different SAR configurations can be obtained. The research on the fixed receiver Bi-static SAR is still on its early stages and it is an interesting research hotspot. READ MORE

  4. 13. Characterization and Reduction of Noise in PET Data Using MVW-PCA

    University essay from Institutionen för informationsteknologi

    Author : Per-Edvin Svensson; [2009]
    Keywords : ;

    Abstract : Masked Volume-Wise Principal Component Analysis (MVW-PCA) is used in Positron Emission Tomography (PET) to distinguish structures with different kinetic behaviours of an administered tracer. In the article where MVW-PCA was introduced, a noise pre-normalization was suggested due to temporal and spatial variations of the noise between slices. READ MORE

  5. 14. 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

  6. 15. Evaluation of the reconstruction algorithm, Ordered Subsets Expectation Maximization, in whole body Positron Emission Tomography

    University essay from Institutionen för medicinsk teknik

    Author : Markus Svensson; [2008]
    Keywords : PET; OSEM; image recontruction; medical imaging;

    Abstract : A Positive Electron Tomography/Computed Tomography devise was installed in theX-ray section at US Linköping in May 2007. Positive Electron Tomography examinations with 18F-fluoro-deoxy-glucose are mainly used for tumor examinations. During 2007 occurred approximately 200 examinations and in 2008 600 are planned.
