  1. 1. Evaluation of FMCW Radar Jamming Sensitivity

    University essay from Uppsala universitet/Signaler och system

    Author : Ludvig Snihs; [2023]
    Keywords : 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;

    Abstract : 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. READ MORE

  3. 2. Software Defined VNA : Measure Coupling Between Elements in an Antenna Array

    University essay from Uppsala universitet/Signaler och system

    Author : Alexander Söderlund; [2023]
    Keywords : VNA; Vector Network Analyser; SDR; KrakenSDR; S-parameter; Antenna Coupling;

    Abstract : With improvements in hardware of antenna receivers, fully digital arrays have been made possible to use in real time systems. These systems have a greater complexity, with the advantage of more dynamic system design since the use of the communication system can be changed with only a software change. READ MORE

  4. 3. Organizational Knowledge Transfer : Exploring possibilities for improvements in knowledge transfer processes within R&D departments

    University essay from Linköpings universitet/Projekt, innovationer och entreprenörskap

    Author : Kristoffer Haglund; Emil Johnsson; [2022]
    Keywords : Absorbing knowledge; collaboration; communication; knowledge transfer; knowledge domain; organization; research and development; spreading knowledge;

    Abstract : Research has established when transferring knowledge, a gap occurs between the sender and receiver due to different expertise. Research has, however, not enlightened how an organization consisting of multiple development departments ensures that individuals with different expertise have the prerequisites needed to transfer knowledge across knowledge domains.

  5. 4. Heterodyne Detection using Frequency-Modulated Continuous-Wave LiDAR

    University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

    Author : Fredrik Johansson; [2020]
    Keywords : lidar; laser; light detection and ranging; heterodyne detection; homodyne detection; Physics and Astronomy;

    Abstract : Light Detection and Ranging (LiDAR) is a technique that can change the way automated systems interact with their environments. The most common LiDAR systems used in industry today are based on the concept of Time-of-Flight (ToF) and utilizes pulsed lasers. READ MORE

  6. 5. Statistical Analysis of Equalization Enhanced Phase Noise in Coherent Fiber Optical Communications

    University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Author : Thomas Gaudy; [2016]
    Keywords : ;

    Abstract : Coherent optical communications increase the receiver sensitivity and the total capacity. Together with high speed digital signal processing (DSP), compensation for linear transmission impairments (chromatic dispersion, polarization mode dispersion and phase noise) can be achieved.
