  1. 1. Doppler radar odometry for localization in difficult underground environment

    Uppsats för yrkesexamina på grundnivå, Örebro universitet/Institutionen för naturvetenskap och teknik

    Författare :Emil Fritz; Annika Nilsson; [2023]
    Nyckelord :SLAM; Localization; Mappers; Odometry; Drift; RIO; Radar; Lidar; IMU;

    Sammanfattning : Accurate and efficient localization is a fundamental requirement for autonomous operation of robots, especially in areas that deny global navigation services. Localization is even more challenging in environments that present visual and geographic difficulties. LÄS MER

  3. 2. Utvärdering av individuella skillnader hos mikrovågssensorer

    M1-uppsats, Jönköping University/JTH, Datateknik och informatik

    Författare :Andreas Svensson; William Jangren; [2020]
    Nyckelord :Microwave sensors; Individual differences; MDU2000; radiation pattern; FFT; RMS; signal strength; Mikrovågssensor; individuell skillnad; MDU2000; strålningsmönster; FFT; RMS; signalstyrka;

    Sammanfattning : The purpose of this study is to investigate if individual differences exists between microwave sensors from the same manufacturer and to find which variables of the microwave sensors that can be the reason for those individual differences. To investigate this, an experiment environment was made to gather data from microwave sensors in a repetitive way. LÄS MER

  4. 3. Security creating technology for elderly care

    Master-uppsats, Jönköping University/JTH, Industridesign

    Författare :Robin Bengtsson; [2020]
    Nyckelord :Elderly care; sense of coherence; gerontology; human centered design; doppler radar technology; product development; radar; camera; industrial design; Äldreomsorg; känsla av sammanhang; gerontologi; användarcentrerad design; dopplerradarteknologi; produktutveckling; radar; kamera; industri design;

    Sammanfattning : The aging population is growing and as more elderly need nursing the demand on elderly care is increasing. There is a risk of not having enough staff in an industry that already lacks educated staff. Many of the employees also complain that they are stressed out. LÄS MER

  5. 4. Evaluation of Commercial Radar Sensors for Proximity Fuze Applications

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

    Författare :Sara Johansson; [2019]
    Nyckelord :;

    Sammanfattning : Radar sensors has been known for their usage in military applications but during the last decade commercial radar sensors have been implemented for usage in for example advanced driver-assistance system. One common implementation for advanced driver-assistance system is the adaptive cruise control technology implemented in vehicles to help it adapt the velocity based on the distance to a detected vehicle in front.

  7. 5. A Study and Modelling of Chaff Clouds Affected by Wing-Tip Vortices

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Jonathan Persson; Jakob Warlin; [2019]
    Nyckelord :chaff study modelling aerodynamics wing-tip vortices; Technology and Engineering;

    Sammanfattning : Chaff are thin strips of either metal or metal coated fibres used as countermeasures against radar. When deployed from an airplane, the turbulence and wing-tip vortices from the airplane disperse the chaff into a chaff cloud, which may appear as a false target and jam the radar. LÄS MER
