1. 1. Enhanced SAR Image Processing Using A Heterogeneous Multiprocessor

   Uppsats för yrkesexamina på grundnivå, Institutionen för datavetenskap

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

   Sammanfattning : 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”. LÄS MER

3. 2. Fast Factorized Back-Pro jection in an FPGA

   Magister-uppsats, Sektionen för Informationsvetenskap, Data– och Elektroteknik (IDE)

   Författare :Andreas Hast; Lars Johansson; [2006]
   Nyckelord :Fast Factorized Back Projection; FFBP; Algorithms;

   Sammanfattning : The Fast Factorized Back Pro jection (FFBP) algorithm is a computationally efficient algorithm for image formation in a Very High Frequency Synthetic Aperture Radar (VHF SAR) system. In this report an investigation of the feasibility of using an FPGA with a hard CPU core to calculate the FFBP in real-time has been done. LÄS MER
