  1. 1. Ash distribution and cavities in Icelandic glaciers, a marker for snow accumulation and radar signal velocity change

    Master-uppsats, Göteborgs universitet/Institutionen för geovetenskaper

    Författare :Andrea Håkansson; [2020-01-15]
    Nyckelord :Iceland; GPR; CMP; Glacier; Vatnajökull; Háabunga; Langjökull;

    Sammanfattning : Glaciers in the geologically active Iceland has a high scientific as well as touristic value.In this thesis, the two largest glaciers on Iceland have been studied with GPR to find ifthe method is suitable to use in future glaciolocial studies where accumulation patternsand similar attributes are in focus in a world of deglaciation.

  2. 2. eBike Radars for Increased Safety

    Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

    Författare :Rebecka Lindquist; Andreas Thoft; [2020]
    Nyckelord :eBikes; radars; safety systems; blind spot; algorithm development; Technology and Engineering;

    Sammanfattning : The purpose of this thesis is to develop a blind spot detection system for increased safety and comfort for a biker. The solution is based on power-efficient small A111 radars, developed by Acconeer AB, which have a range up to seven meters while consuming only a few milliwatts. LÄS MER

  3. 3. Hand Gesture Classification using Millimeter Wave Pulsed Radar

    Master-uppsats, Lunds universitet/Matematisk statistik

    Författare :Eda Dagasan; [2020]
    Nyckelord :Hand Gesture Classification; Millimeter Wave Radar; Statistical Signal Processing; Time-Frequency Analysis; Room Impulse Response Estimation; Sparse Dictionary Learning; Classification; Supervised Learning; Convolutional Neural Networks; k-Nearest Neighbor; Mathematics and Statistics;

    Sammanfattning : Millimeter wave pulsed radar has found many applications, among them hand gesture sensing, which this work has as purpose. This application has already shown good potential, [1], and here in this work robustness aspects are taken into account. LÄS MER

  4. 4. Evaluation of CNN in ESM Data Classification by Perspective of  Military Utility

    Uppsats för yrkesexamina på grundnivå, Försvarshögskolan

    Nyckelord :CNN; emitter classification; ESM; spectrogram; military utility; CNN; sändarklassifikation; ES; ESM; spektrogram; militär nytta;

    Sammanfattning : Modern society has seen an increase in automation using AI in a variety of applications. To keep up with recent development, it is therefore logical to investigate the application of AI programs to military tasks. LÄS MER

  5. 5. Machine Learning for FMCW Radar Interference Mitigation

    Master-uppsats, Lunds universitet/Matematisk statistik

    Författare :Jessica Nilsson; Ludvig Hassbring; [2020]
    Nyckelord :FMCW radar; interference mitigation; convolutional neural network; Mathematics and Statistics;

    Sammanfattning : Frequency Modulated Continuous Wave radar is used for object detection and localization, e.g., for surveillance purposes or for automotive systems. The amount of radars is increasing, which leads to an increasing amount of radar interference. LÄS MER
