  1. 11. Characterisation and Modeling of RF environment

    University essay from Uppsala universitet/Signaler och system

    Author : Patric Beas Petersson; [2022]
    Keywords : signal processing; passive radar; antenna array; data processing; signalbehandling; passiv radar; antennarray; databehandling;

    Abstract : Devices that transmit and receive electromagnetic signals are today central to the way people communicate and acquire information from the surroundings. WiDAR, Wideband Digital Array Receiver, is the name of a new system of digital antenna array receivers, which has recently been developed at Saab in Järfälla and is the focus of this thesis.

  3. 12. Ultra-wideband location tracking of mobile devices

    University essay from Uppsala universitet/Signaler och system

    Author : Daniel Hietarinta; [2022]
    Keywords : UWB; ultra-wideband; GPS; tracking; locating; wireless communication; low-power; embedded systems; mobile devices; OTG; sensors; sensor fusion; mobile app; Android; dynamic anchors; ranging; C; Python;

    Abstract : Today’s most widely used tracking solutions for consumers involve the Global Positioning System (GPS) which meets most needs when it comes to rough estimation of location. GPS however is limited in accuracy with a horizontal error of around 5 meters and cannot be used in the areas where the satellites cannot provide a strong enough signal e.g. READ MORE

  4. 13. Ultra-wideband People Counter

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Murali Tejeshwar Janaswami; [2022]
    Keywords : ;

    Abstract : People counters built using wireless technologies(for example, Wi-Fi or Bluetooth) can better estimate the people count if they can detect and handle false trajectories of people. One way to detect false trajectories is to continuously measure how far a person is from the people counter. READ MORE

  5. 14. Development Of Lung Phantoms for Detection Of Acute Respiratory Distress Syndrome

    University essay from Uppsala universitet/Institutionen för materialvetenskap

    Author : Wassim Wahbeh; Youssef Hasan; [2022]
    Keywords : DARDS;

    Abstract : The goal of this project was to fabricate a deflated and an inflated phantom to replicate how the human lung tissues’ permittivity changes under a pathological condition for instance acute respiratory distress syndrome (ARDS). Furthermore, the lung phantom should be shaped like real human lungs. READ MORE

  6. 15. The Effect of Distortions Induced by Adaptive Antenna Arrays in GNSS Applications

    University essay from Linköpings universitet/Kommunikationssystem; Linköpings universitet/Tekniska fakulteten

    Author : Emma Beskow; [2022]
    Keywords : GNSS; GPS; Jamming; Beamforming; Adaptive antenna arrays; Frequency response distortions;

    Abstract : Global Navigation Satellite Systems (GNSS) are vital tools for accurate navigation and timing for both civil and military use. Due to the low power of the GNSS signals, these systems are sensitive to interference attacks. For wideband GNSS jamming, adaptive antenna arrays are commonly used to suppress interference. READ MORE
