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

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

    Abstract : 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. READ MORE

  7. 5. Millimeter-Wave High-Gain Antenna for 5G Backhauling with Auto-beam-tracking Function

    Author : Enlin Wang; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; gap waveguide; auto-beam-tracking; 5G backhaul; Ultra-high-gain antenna; me- chanical movement;

    Abstract : As microwave links are increasingly deployed within the millimeter-wave frequency range, E-band (70/80 GHz) links have been installed on a global scale. One major technological challenge in this high-frequency spectrum is the significant increase in path loss between receivers and transmitters. READ MORE
