3. 2. SAR Image Focus Errors due to Incorrect Geometrical Positioning in Fast Factorized Back-Projection

   Författare :Annelie Wyholt; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Back-Projection; topography effects; range distortions; Autofocus; SAR;

   Sammanfattning : Synthetic Aperture Radar, SAR, is an aperture synthesis technique to generate an image of the ground from air or space with high resolution. Signal processing is performed in frequency domain with Fourier Transform techniques, or in time domain with Back Projection techniques. LÄS MER

4. 3. Factorized Geometrical Autofocus for Synthetic Aperture Radar Processing

   Författare :Jan Torgrimsson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Back-Projection; PGA; SAR; UWB; Autofocus; FGA;

   Sammanfattning : Synthetic Aperture Radar (SAR) imagery is a very useful resource for the civilian remote sensingcommunity and for the military. This however presumes that images are focused. There are severalpossible sources for defocusing effects. For airborne SAR, motion measurement errors is the maincause. LÄS MER
