  1. 1. Classification of Radar Emitters using Semi-Supervised Contrastive Learning

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

    Author : Tim Jonsson; [2023]
    Keywords : ;

    Abstract : Radar is a commonly used radio equipment in military and civilian settings for discovering and locating foreign objects. In a military context, pilots being discovered by radar could have fatal consequences. READ MORE

  3. 2. Offline Direction Clustering of Overlapping Radar Pulses from Homogeneous Emitters

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

    Author : Sofia Bedoire; [2022]
    Keywords : Clustering; DBSCAN; Deinterleaving; Machine Learning; Radar; Klustring; DBSCAN; Pulssortering; Maskininlärning; Radar;

    Abstract : Within the defence industry, it is essential to be aware of threats in the environment. A potential threat can be detected by identifying certain types of emitters in the surroundings that are typically used in the enemies’ systems. READ MORE

  4. 3. Out-of-distribution Recognition and Classification of Time-Series Pulsed Radar Signals

    University essay from KTH/Matematisk statistik

    Author : Paul Hedvall; [2022]
    Keywords : Out-of-Distribution; Gaussian Mixture Models; Dirichlet Process Mixture Models; Deinterleaving; Radar classification; Time-series analysis; Pulsed radar signals; Out-of-Distribution; Gaussian Mixture Models; Dirichlet Process Mixture Models; Deinterleaving; Radar classification; Time-series analysis; Pulsed radar signals;

    Abstract : This thesis investigates out-of-distribution recognition for time-series data of pulsedradar signals. The classifier is a naive Bayesian classifier based on Gaussian mixturemodels and Dirichlet process mixture models. READ MORE

  5. 4. AI-based Classification of Radar Signals

    University essay from Lunds universitet/Matematisk statistik

    Author : Ludwig Hollmann; Max Fors Joki; [2021]
    Keywords : Neural networks; TensorFlow; Keras; Radar signals; Mathematics and Statistics;

    Abstract : Military vehicles typically send out radar signals in order to detect their surroundings. Using an Electromagnetic Support Measures receiver, these can be detected and it is of interest to be able to classify them in order to identify the vehicle and type of radar. READ MORE

  6. 5. Automation of Pulse Repetition Interval Modulation Classification

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

    Author : Karolina Barrios; [2021]
    Keywords : ;

    Abstract : Radar systems are essential in the field of electronic warfare and radar signals are used for estimating speed, location and direction of an object. A radar system sends out small transmissions called pulses. The interval between the start of one pulse to the start of the next pulse is called pulse repetition interval (PRI). READ MORE
