1. 1. An Evaluation of Interpolation and Oversampling Effects on Image Quality in Synthetic Aperture Radar Processing with Global Back-projection

   University essay from Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandling

   Author : Andreas Hartman; [2014]
   Keywords : Synthetic Aperture Radar; Global Back-projection; Image Quality; Side Lobe Suppression;

   Abstract : For time domain SAR processing algorithms, such as Global Back-projection, interpolation becomes a part of the implementation. In order for the interpolation to yield good results, the oversampling rate used in the sampling of the original data may constitute an important factor. READ MORE

3. 2. 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

4. 3. 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. 4. Fast Factorized Back-Pro jection in an FPGA

   University essay from Sektionen för Informationsvetenskap, Data– och Elektroteknik (IDE)

   Author : Andreas Hast; Lars Johansson; [2006]
   Keywords : Fast Factorized Back Projection; FFBP; Algorithms;

   Abstract : 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. READ MORE
