  1. 1. Waveform agility for robust radar detection and jamming mitigation

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

    Författare :Karl-Johan Hällgren; [2021]
    Nyckelord :radar; electronic warfare; jamming; jamming resistance; waveforms; phase codes; MIMO; radar; telekrig; störning; störskydd; vågformer; faskoder; MIMO;

    Sammanfattning : In this report metrics for jamming resistance and radar performance of waveform sets are described and developed, and different sets of waveforms are optimized, evaluated and compared. It is shown that without additional processing or PRI jitter, waveform sets can reach jamming resistance a few dB worse than what is provided by PRI jitter alone, and together with PRI jitter a few dB better.

  3. 2. 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.

  4. 3. Construction of a fusion protein for anchoring the inflammatory receptor NLRP3 to the cell membrane

    Kandidat-uppsats, Högskolan i Skövde/Institutionen för biovetenskap

    Författare :Rebecca Ling; [2019]
    Nyckelord :NLRP3 inflammasome; Overlap PCR; Fusion Protein; LPI™ technology;

    Sammanfattning : The innate immune system are a cooperation of many components – receptors being one of them. Both membrane-bound and cytosolic receptors play a large role in the defence system against pathogens and danger. LÄS MER

    Sammanfattning : Sedan radar började användas under första hälften av 1900-talet har duellen mellan radar och signalspaning pågått. Genom att utnyttja radar har alltid en medveten risk tagits, risken att bli upptäckt av motståndarens signalspaning. LÄS MER
