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

    University essay from Linköpings universitet/Reglerteknik

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

    Abstract : 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. READ MORE

  3. 2. Spatialisation of Binaural Audio With Head Tracking in First-Person Computer Games

    University essay from Stockholms universitet/Institutionen för data- och systemvetenskap

    Author : Patrik Bergsten; Mikita Kihan; [2023]
    Keywords : Sound localisation; head tracking; binaural; audio; computer games; experiences;

    Abstract : Audio in today’s first person computer games plays a vital role in informing players about their surroundings as well as general gameplay elements. Awareness of the direction, distance, and spatial placement of audio sources can be crucial for players in various contexts. READ MORE

  4. 3. Effects of reconstruction parameters on the image quality and quantification of PET images from PET/MRI and PET/CT systems

    University essay from

    Author : Ali Amena Hussain; [2022-03-09]
    Keywords : Medical physics; PET CT; PET MRI; OSEM; BPL; NEMA IQ; positron emission tomography; magnetic resonance imaging; computed tomography; ordered Subset Expectation Maximization; The Bayesian Penalized Likelihood;

    Abstract : Aim: To study how reconstruction parameters affect the positron emission tomography (PET) image quality and quantitative results for the different lesion to background radioactivity ratios in three different PET systems. Introduction: Multimodality imaging that combines magnetic resonance imaging (MRI) or computed tomography (CT) with a PET system can produce medical images containing both functional and anatomical information.

  5. 4. High-Performance Beamforming for Radar Technology : A Comparative Study of GPU Beamforming Algorithms

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Oscar Lindgren; [2022]
    Keywords : Accelerated signal processing software; Beamforming; Electronic warfare; Electromagnetic waves; Emitter identification; Radar technology; Accelererad signalbehandlingsmjukvara; Beamforming; Elektronisk krigsföring; Elektromagnetiska vågor; Sändaridentifikation; Radarteknologi;

    Abstract : Radar technology is widely used in today´s society, whether it is the localisation and identification of aircraft in air traffic control systems, ships in harbour management systems, or the weather forecast presented on the news. In military applications, such as in fighter jets or missile lock-on systems, the speed at which the radar processes incoming data is essential to ensure a successful outcome. READ MORE

  6. 5. Radio signal detection and localisation for uncovering unauthorised signals in an examination environment

    University essay from Göteborgs universitet/Institutionen för data- och informationsteknik

    Author : Marcus Adler; Otto Lundin; Lam Nguyen; Nour Alddin Taki; [2021-09-14]
    Keywords : Cheating; Anti-cheat; Cheat-detection; Radio signal detection; Multilateration; SDR; ADALM-PLUTO; Signal localisation;

    Abstract : Examination is a fundamental part of education, both for students and institutions. Cheating on exams is something educational institutions are trying to reduce. One form of cheating is the use of a mobile phone to live-stream the exam to pass the test. READ MORE
