  1. 6. LPI waveforms for AESA radar

    University essay from Uppsala universitet/Fasta tillståndets elektronik

    Author : Andreas Sjöberg; [2020]
    Keywords : Radar LPI waveform AESA;

    Abstract : 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.

  3. 7. Deinterleaving of radar pulses with batch processing to utilize parallelism

    University essay from KTH/Kommunikationssystem, CoS

    Author : Emma Lind; Mattias Stahre; [2020]
    Keywords : Cluster analysis; DBSCAN; Parallelization; Signal Separation; Unsupervised learning; Klusteranalys; DBSCAN; Parallellisering; Signal Separation; Oövervakat lärande;

    Abstract : The threat level (specifically in this thesis, for aircraft) in an environment can be determined by analyzing radar signals. This task is critical and has to be solved fast and with high accuracy. The received electromagnetic pulses have to be identified in order to classify a radar emitter. READ MORE

  4. 8. Pulse Repetition Interval Generation using Deep Learning

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Michaela Jangefalk; [2020]
    Keywords : ;

    Abstract : Radar is a central system in the field of electronic warfare used to estimate an object’s location, speed, and direction. A pulse radar emits pulses at predetermined time intervals. READ MORE

  5. 9. Deinterleaving pulse trains with DBSCAN and FART

    University essay from Uppsala universitet/Avdelningen för systemteknik

    Author : Shad Mahmod; [2019]
    Keywords : DBSCAN; FART; Fuzzy; Adaptive; Resonance; Theory; Radar; Clustering; Deinterleaving; Machine Learning;

    Abstract : Studying radar pulses and looking for certain patterns is critical in order to assess the threat level of the environment around an antenna. In order to study the electromagnetic pulses emitted from a certain radar, one must first register and identify these pulses. READ MORE

  6. 10. Pulse Repetition Interval Modulation Classification using Machine Learning

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Eric Norgren; [2019]
    Keywords : machine learning; radar; radar pulses; radar signals; pulseradar; pulse repetition interval; modulation; classification; LSTM; long short term memory; feature extraction; saab; ai; artifical intelligence; radar warning receiver; rwr; neural network; maskininlärning; radar; radarpulser; radar signaler; pulsradar; pulsrepetitionsintervall; modulationstyp; modulering; klassificering; LSTM; long short term memory; särdrag; saab; ai; artificiell intelligens; radarvarnare; rwr; neuralt nätverk;

    Abstract : Radar signals are used for estimating location, speed and direction of an object. Some radars emit pulses, while others emit a continuous wave. Both types of radars emit signals according to some pattern; a pulse radar, for example, emits pulses with a specific time interval between pulses. READ MORE
