    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

  3. 2. Validation of an implementation of MBSE and the possibility of Simulating System Models

    Master-uppsats, KTH/Matematik (Avd.)

    Författare :Yasmin Chaoui El Kaid; [2021]
    Nyckelord :;

    Sammanfattning : Model-Based Systems Engineering (MBSE) is the process of developing a set of system models that help define, design and document a system under development. These models provide an efficient way to explore, update, and communicate system perspectives to stakeholders, while eliminating dependence on traditional documents. LÄS MER

  4. 3. Elektronisk krigföring mot sensorer i varnar- och motverkanssystem

    Uppsats för yrkesexamina på grundnivå, Försvarshögskolan

    Författare :Jesper Nilsson; [2021]
    Nyckelord :APS; DAS; Electronic warfare; Jamming; Arena; Afghanit; VMS; APS; DAS; aktiv radarstörning; telekrig; Arena; Afghanit; varnare och motverkanssystem;

    Sammanfattning : This report on the subject of Systems Science for Defence and Security, aims to study the possibility for electronic warfare (EW) against the radar in active protection system (APS) on ground combat vehicles. The goal of the EW is to ensure effect of current anti-tank systems against an enemy equipped with APS. LÄS MER

  5. 4. Systems methodology for Analysis of Airborne Electronic Warfare Systems

    Master-uppsats,

    Författare :Hugo Hedén; [2021]
    Nyckelord :Survivability; EW; ECM; ECCM; Systems methodology; influence diagram; multi-agent influence diagram; defence systems; försvarssystem;

    Sammanfattning : This report is one of the first to examine how system methodology can be applied as a tool to facilitate a holistic view of fighter aircraft survivability. This is done through the application of a modified version of multi-agent influence diagrams (MAIDs), as an analytical tool of two generic one-on-one scenarios based on Robert E. LÄS MER

  7. 5. LPI waveforms for AESA radar

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Fasta tillståndets elektronik

    Författare :Andreas Sjöberg; [2020]
    Nyckelord :Radar LPI waveform AESA;

    Sammanfattning : The purpose of low probability of intercept (LPI) radar is, on top of the standard requirements on a radar, to remain undetected by hostile electronic warfare (EW) systems. This can be achieved primarily by reducing the amount of radiated power in any given direction at all times and is done by transmitting longer modulated pulses that can then be compressed digitally in order to retain range resolution.
