1. 6. 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. 7. Teleoperation of an Autonomous Ground-Penetrating Radar for Non-Destructive Surveying: Design and Implementation

   Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysik

   Författare :Rasmus Beyer; [2023]
   Nyckelord :Autonomous; GPR; Robotics;

   Sammanfattning : A lot of features that need to be scanned underground should not be disturbed, from waterlines to unmarked graves. A non-invasive way of probing underground is Ground-Penetrating Radar (GPR). GPR finds differences in materials with radar waves. However, GPR is human-operated and its position is generally determined with a GPS. LÄS MER

4. 8. Digitally Controlled Oscillator Topologies for mm-Wave Pulsed Coherent Radar

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

   Författare :Klas Junskog; [2023]
   Nyckelord :oscillators; mm-wave; radar; Technology and Engineering;

   Sammanfattning : The advancement of future generations of wireless communication and radar sensing warrants the need for mm-wave digitally controlled oscillators (DCOs) with high-frequency trade-offs in consideration. The purpose of this project is to investigate DCO topologies inspired from scientific literature. LÄS MER

5. 9. Exploration of Radar Cross Section Models and Distributed Sensing Techniques in JCAS Cell-free Massive MIMO

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Qinglin Zou; [2023]
   Nyckelord :Joint communication and sensing; Cell-free massive MIMO; Swerling models; Distributed Sensing; Gemensam kommunikation och avkänning; Cellfri massiv MIMO; Swerling modeller; Distributed Sensing;

   Sammanfattning : Joint Communication and Sensing (JCAS) technology enables the sharing of infrastructure, resources, and signals between communication and sensing. However, studying the performance and algorithms using appropriate target reflectivity models for detection poses a significant challenge. LÄS MER

7. 10. Multidimensional Classification of Radar Signals : A comparison between unidimensional and multidimensional classification models for pulsed radar signals

   Master-uppsats, Umeå universitet/Institutionen för datavetenskap

   Författare :Max Ek Törmä; [2023]
   Nyckelord :pulsed radar classification; Bayesian Gaussian mixture models; Dirichlet process mixture models; multidimensional radar classification; pulsed radar signals; radar signal classification;

   Sammanfattning : Radar is a technique used by many different types of remote sensing systems to keep track of their surroundings. The transmitted radar signals may carry information that could be used to infer the type of transmitter. Multiple papers have investigated the classification of pulse repetition intervals produced by radar systems. LÄS MER
