  1. 1. Surface Reconstruction using Multipath Propagation in Indoor MIMO Radar

    Master-uppsats, Lunds universitet/Matematisk statistik

    Författare :Elias Olson; Jakob Henningsson; [2023]
    Nyckelord :Multiple-input multiple-output MIMO radar; multipath recognition; geometry reconstruction; Mathematics and Statistics;

    Sammanfattning : Using active radar for localization in indoor environments is challenging. By signal reflection off walls and other static objects, false targets occur, referred to as multipath "ghosts". These are a significant hinder in interpreting the data. LÄS MER

  3. 2. 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.

  4. 3. Pose classification of people using high resolution radar indoor

    Master-uppsats, Lunds universitet/Matematik LTH

    Författare :Anton Almqvist; Anton Kuusela; [2022]
    Nyckelord :indoor radar; FMCW radar; point cloud; classification; Machine learning; Deep learning; PointNet; Technology and Engineering;

    Sammanfattning : Video cameras are the primary equipment used for indoor surveillance. There are however areas where alternatives are needed as the use of cameras is sensitive or forbidden, e.g. in homes, bathrooms or dressing rooms. LÄS MER

  5. 4. Millimeter Wave Radar as Navigation Sensor on Robotic Vacuum Cleaner

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Anneli Blomqvist; [2020]
    Nyckelord :Millimeter wave radar; Robotic vacuum cleaner; Indoor navigation; Localization; Obstacle Detection; Millimeter radar; Robotdammsugare; Navigering inomhus; Positionering; Hinderdetektion;

    Sammanfattning : Does millimeter-wave radar have the potential to be the navigational instrument of a robotic vacuum cleaner in a home? Electrolux robotic vacuum cleaner is currently using a light sensor to navigate through the home while cleaning. Recently Texas Instruments released a new mmWave radar sensor, operating in the frequency range 60-64 GHz. LÄS MER

  7. 5. 3-D Positioning in Large Warehouses using Radio-frequency identification

    Master-uppsats, Linköpings universitet/Kommunikationssystem; Linköpings universitet/Tekniska högskolan

    Författare :Jonas Karhu; [2014]
    Nyckelord :RFID; Positioning;

    Sammanfattning : In large warehouses, there are a lot of articles that needs do be kept track of. As the number of articles grows larger, the administrative complexity increases. Thus, a solution that automatically keeps track of the position of each article in real-time is of interest. LÄS MER
