  1. 1. Exploring Near-Field SAR with mmWave Pulsed Coherent Radar

    Master-uppsats, Lunds universitet/Matematisk statistik

    Författare :Elina Yrlid; [2023]
    Nyckelord :SAR; Synthetic Aperture Radar; PCR; pulsed coherent radar; radar; mmWave; millimeter-wave; near-field; 60GHz; Technology and Engineering;

    Sammanfattning : This thesis explores the option to apply Synthetic Aperture Radar (SAR) techniques to image near-field targets utilizing mmWave pulsed coherent radar (PCR). The recent development of mmWave radars has broadened the scope for SAR, but there are few concrete examples explaining and demonstrating the fundamental SAR algorithms from a PCR perspective.

  4. 3. SAR imaging with a hand-held UWB radar system

    Magister-uppsats, Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Författare :Alexander Rajula; [2012]
    Nyckelord :handheld; imaging; radar; SAR;

    Sammanfattning : Synthetic aperture radar (SAR) systems are used extensively for imaging vast areas using electromagnetic radiation. Radar systems have the benefit of being able to image areas which optical light cannot pass through, which makes them suitable for surveillance and weather monitoring, or monitoring through difficult atmospheric conditions.
