1. 1. Integrated Sensing and Communicationusing OFDM and Stepped FMCWSignals : Proof-of-Concept and Evaluation with Software DefinedRadios

   Master-uppsats, Blekinge Tekniska Högskola/Fakulteten för datavetenskaper

   Författare :Sai Chetan Poluri; Tejaswi Dunuka; [2023]
   Nyckelord :5G and 6G Communications; FMCW; GNU Radio; ISAC; OFDM; SDR; Sensing; JSAC;

   Sammanfattning : The thesis work shows the implementation of sensing and communication, so a basic knowledge of analog and digital communication systems is needed to understand this paper Background. With the increase in smart devices, the bandwidth requirements are increased, which created congestion in the radio spectrum resources. LÄS MER

3. 2. Evaluation of FMCW Radar Jamming Sensitivity

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

   Författare :Ludvig Snihs; [2023]
   Nyckelord :FMCW; FMCW radar; radar; frequency-modulated radar; noise jamming; frequency-modulated continuous wave radar; FMCW Jamming; Jamming; Pulse Train; Pulse Jamming; Spoofing Attack; Spoofing; Deception; Repeater Jamming; Repeater; Automotive Radar; CFAR; sensor jamming; constant false alarm rate; electronic warfare; EW; FMCW; FMCW radar; frekvensmodulerad dopplerradar; dopplerradar; radar; brusstörning; radarstörning; pulsstörning; pulståg; falskmål; vilseledning; repeterstörning; bilradar; sensorstörning; CFAR;

   Sammanfattning : In this work, the interference sensitivity of an FMCW radar has been evaluated by studying the impact on a simulated detection chain. A commercially available FMCW radar was first characterized and its properties then laid the foundation for a simulation model implemented in Matlab. LÄS MER

4. 3. Evaluation of algorithms for accurate micro-doppler effects measurement in FMCW radar

   Master-uppsats, Linköpings universitet/Fysik, elektroteknik och matematik; Linköpings universitet/Tekniska fakulteten

   Författare :Morgan Agerstig Rosenqvist; [2023]
   Nyckelord :Radar; FMCW; micro-Doppler; RPM;

   Sammanfattning : Micro-Doppler effects are phenomena that occur because of micro-motion. A micro-motion is either a vibration, rotation, or acceleration which is small relative to the motion of the target. These effects can be used in order to characterize a target through their signature movement. LÄS MER

5. 4. 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

7. 5. Reconnaissance Radar Robot

   Uppsats för yrkesexamina på grundnivå, Högskolan i Halmstad/Akademin för informationsteknologi

   Författare :Kasper Holm; Erik Henrysson; [2023]
   Nyckelord :radar; signal; processing; signal processing; state; machine; state machine; test; testing; radar testing; radar technology; frequency modulated continuous wave; fmcw; pulse radar; raspberry pi; single board computer; sbc; poe; power over ethernet; mqtt; mqtt package; python; drones; uav; unmanned aerial vehicle; drone detection; radar robot; swedish armed forces; swedish armed forces technical school; fmts; beamforming; fast fourier transform; fft; point cloud; point clustering; software design;

   Sammanfattning : During the last century, various countries' armed forces have used unmanned aerial vehicles, commonly known as drones. In recent years, strives have been made to develop small commercial drones that have allowed the general public to afford and use them for recreational purposes. LÄS MER
