  1. 1. Direct Signal Interference Suppression and Target Detection for Low-Cost SDR-Based Passive Bistatic Radar

    Master-uppsats, Linköpings universitet/Reglerteknik

    Författare :Oskar Jonsson; [2022]
    Nyckelord :passive radar; ECA; LMS; software-defined radio;

    Sammanfattning : Passive radar is a technology for detection of targets using echoes of existing radio transmitter, such as FM-radio. Since only receivers are needed for operation, a passive radar system has the possibility of being implemented using low-cost hardware. LÄS MER

  4. 4. Using Software-Defined Radio for ATN B1 : A look into CPDLC encoding and VDL Mode 2 transmission

    Kandidat-uppsats, Linköpings universitet/Institutionen för datavetenskap; Linköpings universitet/Tekniska fakulteten

    Författare :Vilhelm Melkstam; Anton Magnusson; [2022]
    Nyckelord :CPDLC; ATN B1; VDL Mode 2; Software-Defined Radio; Air Communication; Security;

    Sammanfattning : An essential part of European air traffic control is the Aeronautical Telecommunications Network Baseline 1 (ATN B1) specification. This paper sheds some light on Controller–Pilot Data Link Communications (CPDLC) and VHF Data Link Mode 2 (VDL Mode 2), two crucial components of ATN B1. LÄS MER

  5. 5. Radio signal detection and localisation for uncovering unauthorised signals in an examination environment

    Kandidat-uppsats, Göteborgs universitet/Institutionen för data- och informationsteknik
