  1. 1. Robust Aircraft Positioning using Signals of Opportunity with Direction of Arrival

    Master-uppsats, Linköpings universitet/Reglerteknik

    Författare :Erik Axelsson; Sebastian Fagerstedt; [2023]
    Nyckelord :Simultaneous localisation and mapping; direction of arrival; signals of opportunity; extended Kalman filter; positioning;

    Sammanfattning : This thesis considers the problem of using signals of opportunity (SOO) with known direction of arrival (DOA) for aircraft positioning. SOO is a collective name for a wide range of signals not intended for navigation but which can be intercepted by the radar warning system on an aircraft. LÄS MER

  3. 2. Detection and Tracking of Elephants using Seismic Direction of Arrival Estimates

    Master-uppsats, Linköpings universitet/Reglerteknik

    Författare :Albin Westlund; Daniel Goderik; [2023]
    Nyckelord :Wildlife Conservation; DOA Estimation; Geophone Array; Target Tracking; Elephant Detection;

    Sammanfattning : As human settlement expands into the natural habitats of wild animals, the conflict between humans and wildlife increases. The human-elephant conflict is one that causes a tremendous amount of damage, often to poor villages close to the savannah. LÄS MER

  4. 3. ESPRIT for DOA estimation

    Kandidat-uppsats, Högskolan i Halmstad/Akademin för informationsteknologi

    Författare :Filip Grimsholm; Martin Saarmann; [2023]
    Nyckelord :ESPRIT; FMCW; DOA; radar; estimation; comparison; ESPRIT; FMCW; DOA; radar; estimering; jämförelse;

    Sammanfattning : Radar is a tool that has had a tremendous impact since its discovery. This thesis evaluates an algorithm called ESPRIT. ESPRIT is used in radar to estimate the angles to detected objects. The angle of an object is referred to as its DOA (Direction of arrival). LÄS MER

  5. 4. A Study of Direction of Arrival Methods Based on Antenna Arrays in Presence of Model Errors.

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Signaler och system

    Författare :Julia Sjödin; [2022]
    Nyckelord :Direction of Arrival; DOA; WSF; MUSIC; TLS-ESPRIT; Extended Kalman filter; model error;

    Sammanfattning : Methods for Direction of Arrival, DOA estimation of multiple objects based on phased arrayantenna technology have many advantages in for example electronic warfare and radarapplications. However, perfect calibration of an antenna array can seldom be achieved. LÄS MER

  7. 5. Improved Accuracy for Indoor Positioning with Bluetooth 5.1: From Theory to Measurements

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

    Författare :Victor Sesma Santos; Victor Egorov; [2020]
    Nyckelord :Technology and Engineering;

    Sammanfattning : In this thesis we are evaluating Bluetooth Low Energy (BLE) v5.1 in combination with Direction Of Arrival (DOA) algorithms and receiving antenna arrays for indoor positioning systems. The thesis is divided in two parts. The first part is the core of the thesis and is composed by the evaluation of DOA algorithms in a direction finding system. LÄS MER
