  1. 1. Radar and sea clutter simulation with Unity 3D game engine

    M1-uppsats, Linköpings universitet/Programvara och system

    Författare :Mikael Johnsson; Linus Bergman; [2023]
    Nyckelord :radar simulation; sea clutter simulation; game engine; Unity; ray tracing; compute shader; graphics programming; GPU; radarsimulering; sjöklottersimulering; spelmotor; Unity; strålspårning; compute shader; grafisk programmering; GPU;

    Sammanfattning : Game engines are well known for their use in the gaming industry but are starting to have an impact in other areas as well. Architecture, automotive, and the defence industry are today using these engines to visualise and, to some extent, test their products. LÄS MER

  3. 2. Contribution to the Understanding of the Effects of Propagation through the Ionosphere of P-band SAR Data

    Master-uppsats, Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Författare :Johannes Samuel Erland Rönner; [2023]
    Nyckelord :Synthetic aperture radar; Ionosphere;

    Sammanfattning : The BIOMASS mission from the European Space Agency (ESA) is designed to measurebiomass and carbon content in Earth’s forests. To account for phase changes caused byionospheric variations, a map-drift autofocus algorithm is developed, which utilises a phasescreen of the ionosphere to eliminate phase errors in the signal.

  4. 3. Heart Rate Measurement using a 60 GHz Pulsed Coherent Radar Sensor

    Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

    Författare :Melina Al Nasser; Linn Gromert; [2022]
    Nyckelord :Signal processing; EKG; Heart rate; Radar sensor; Neural network; Acconeer; Technology and Engineering;

    Sammanfattning : Heart rate is today measured in various ways, but they all include contact with the skin. Measuring heart rate contactless would be a more efficient method in healthcare and would also benefit people suffering from skin problems. It has been proven that it is possible to use radar to measure heart rate. LÄS MER

  5. 4. Autonomous Propulsion for a GPR-UGV

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysik

    Författare :Fredrik Wall Eskilsson; [2022]
    Nyckelord :robotics; gpr; autonomous; robot; ros; slam;

    Sammanfattning : This thesis presents the research and development behind the integration of an autonomous propulsion system for a four-wheeled Ground Penetrating Radar (GPR) measurement unit, previously requiring manual operation. In order to ease the administration of the complex new system, Robot Operating System (ROS) 2 was used as middleware, where an implementation of Light Detection And Ranging (LiDAR) 3D-SLAM (Simultaneous Localization And Mapping) served to secure precise localization of the Unmanned Ground Vehicle (UGV) and mapping of its environment.

  7. 5. User Centered Design of a Fall Detection System

    Master-uppsats, Lunds universitet/Innovation

    Författare :Casper Cronberg; Ludwig Darle Olsson; [2022]
    Nyckelord :User Experience; Universal Design; Interaction Design; Technical Design; Welfare Technologies and Elderly Care; Technology and Engineering;

    Sammanfattning : This master thesis has created a concept of a fall detection system for older people. The system is built around new radar technology that will detect a fall accident and then initiate an alarm sequence that will contact the home care. The system is intended to be installed in the home of the user. LÄS MER
