   Nyckelord :CT Imaging; Parallel-Beam Projection; 2D FFT; Radon Transform; Filters; Window Functions; Kaiser window; Inverse Fourier Transform; FBP.;

   Sammanfattning : The traditional Computed Tomography (CT) is based on the Radon Transform and its inversion. The Radon transform uses parallel beam geometry and its inversion is based on the Fourier slice theorem. LÄS MER

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

   Master-uppsats, Blekinge Tekniska Högskola/Avdelningen för signalbehandling

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

   Sammanfattning : 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. LÄS MER
