  1. 1. Micro-Shivering Detection : Detection of human micro-shivering using a 77 GHz radar

    Magister-uppsats, Högskolan i Halmstad/Akademin för informationsteknologi

    Författare :Elyas Razzaghi; Arno Van Hoek; [2019]
    Nyckelord :micro-shivering; vibration; vital signs; mmwave radar; fmcw radar; chirp signal; snr; phase accuracy;

    Sammanfattning : Radars have been under steady development to track, identify, image, and classify targets. Modern radar systems, with the help of embedded systems, have additional comprehensive signal processing capabilities. They can extract useful information from very noisy data, e.g. LÄS MER

  3. 2. Miniaturization of a Low Power Harmonic Radar for UAV use

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

    Författare :Saleh Aljaser; [2019]
    Nyckelord :Harmonic; Radar; Insects; Tracking; Detection; UAV; FMCW; Small; Low Power; Wireless; Communications; Technology and Engineering;

    Sammanfattning : The aim with this Master thesis work is to design, build and test a small size, light weight and low power consumption harmonic radar system that will be installed in a flying drone for the purpose of tracking and localizing tagged Bogong moths near their aestivation caves and crevices in Australia during summer. A FMCW harmonic radar is proposed, it comprises a radar transmitter, receiver and a signal processor. LÄS MER

  4. 3. Airborne Radar Ground Clutter Suppression Using Multitaper Spectrum Estimation & Choosing DPSS Parameters

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Författare :Carl-Henrik Hanquist; [2018]
    Nyckelord :DPSS; Multitaper; Radar;

    Sammanfattning : One of the biggest challenges in any airborne radar is to distinguish a target from a strong ground echo. The main problem is that the ground echo, called ground clutter, can be up to a million times stronger than the response from the target in question. LÄS MER

  5. 4. Airborne Radar Ground Clutter Suppression Using Multitaper Spectrum Estimation : Comparison with Traditional Method

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Författare :Linus Ekvall; [2018]
    Nyckelord :Ground clutter; tapering; multitaper; discrete prolate spheroidal sequences; minumum variance estimation; signal processing; radar; airborne radar;

    Sammanfattning : During processing of data received by an airborne radar one of the issues is that the typical signal echo from the ground produces a large perturbation. Due to this perturbation it can be difficult to detect targets with low velocity or a low signal-to-noise ratio. LÄS MER

  7. 5. Designing an interactive handlebar infotainment system for light vehicles

    Uppsats för yrkesexamina på avancerad nivå, KTH/Skolan för datavetenskap och kommunikation (CSC)

    Författare :Jesper Bratt; [2016]
    Nyckelord :In-vehicle infotainment; Optical gesture interaction; Light vehicles;

    Sammanfattning : This thesis studies what the crucial aspects are when designing and developing an in-vehicle infotainment system for light vehicles that should both extend functionality and improve safety. In order to ground the research, innovations made in automotive infotainment systems are examined and a design for a light vehicle infotainment system that utilizes optical gesture based touch interaction is proposed.
