  1. 1. Target Orientation Detection Using UWB SAR by Implementing Polarimetry Technique

    Master-uppsats, Högskolan i Gävle/Elektronik

    Författare :Amran Ndolla; [2016]
    Nyckelord :;

    Sammanfattning : In a recently started research project which took place at University of Gavle during the year 2015 an ultra-wideband (UWB) synthetic aperture radar (SAR) for non-destructing evaluation of walls was used to detect the metal target (pipe). The SAR used is designed by a small radar company in Gavle called Radarbolaget. LÄS MER

  3. 2. Experiment with Moving Target Focusing using GB-SAR

    Master-uppsats, Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandling

    Författare :Krishna Mani Bajagain; [2014]
    Nyckelord :SAR; GB-SAR; GBP algorithm; Moving target Detection;

    Sammanfattning : Ground Based Synthetic Aperture Radar (GB-SAR) refers to SAR system which is mounted on ground linear track. It works on same principle as conventional SAR. Nowadays GB-SAR plays prominent role in the studies of many natural phenomenon as well as in studying some artificial infrastructure or terrain. LÄS MER
