  1. 1. 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

  2. 2. Measurement of the snow accumulation in Antarctica with a neutrino radio detector and extension to the measurement of the index-of-refraction profile

    University essay from Uppsala universitet/Högenergifysik

    Author : Jakob Beise; [2021]
    Keywords : Askaryan; UHE neutrinos; in-ice radio detection; in-situ detector calibration; deep learning; radio neutrino detector; ARIANNA;

    Abstract : High-energy neutrino physics offers a unique way to investigate the most violent phenomena in our universe. The detection of energies above E > 1017 eV is most efficient using the Askaryan effect, where a neutrino-induced particle shower produces coherent radio emission that is detectable with radio antennas.

  3. 3. Audio-based Motion Detection

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Gopal Gomatam; Filip Dujmic; [2021]
    Keywords : sonar; motion detection; audio frequencies; audio processing; Technology and Engineering;

    Abstract : Motion detection is an essential technology and it has numerous use-cases, such as security tracking, automated door opening systems, and IP cameras. Commonly, passive infrared sensors or radio frequency sensors are used for motion detection. However, this thesis focuses on performing motion detection using existing hardware at audio frequencies.

  4. 4. Development of an underwaterruler using an AUV-deployedbeacon and Matched filter CFARdetector

    University essay from KTH/Marina system

    Author : Yaolin Ge; [2020]
    Keywords : ;

    Abstract : Our ocean covers more than 70% of our planet’s surface. It is a huge reservoir continuously supplying us with enormousvaluable resources. The autonomous aquaculture, deep sea mining, subsea oil / gas exploitation and marine biology etc.,are the increasingly important driving forces for the development of underwater robotics. READ MORE

  5. 5. Design of a UAV-based radio receiver for avalanche beacon detection using software defined radio and signal processing

    University essay from Uppsala universitet/Signaler och System

    Author : Richard Hedlund; [2019]
    Keywords : Signal processing; Software Defined Radio; Avalanche; Beacon; Antenna; SDR; DSP; Signalbehandling; Mjuvarudefinierad Radio; Lavin; Lavinsändare; Antenn; SDR; DSP;

    Abstract : A fully functional proof of concept radio receiver for detecting avalanche beacons atthe frequency 457 kHz was constructed in the work of this master thesis. The radioreceiver is intended to be mounted on an unmanned aerial vehicle (UAV or drone)and used to aid the mountain rescue teams by reducing the rescue time in findingavalanche victims carrying a transmitting beacon.
