1. 1. Dataset Drift in Radar Warning Receivers : Out-of-Distribution Detection for Radar Emitter Classification using an RNN-based Deep Ensemble

   University essay from Uppsala universitet/Avdelningen för systemteknik

   Author : Kevin Coleman; [2023]
   Keywords : Radar Emitter Classification; Pulse Descriptor Word; Out of Distribution Detection; Dataset Drift; Uncertainty Estimation; Deep Ensembles; Recurrent Neural Networks; LSTM;

   Abstract : Changes to the signal environment of a radar warning receiver (RWR) over time through dataset drift can negatively affect a machine learning (ML) model, deployed for radar emitter classification (REC). The training data comes from a simulator at Saab AB, in the form of pulsed radar in a time-series. READ MORE

3. 2. 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

4. 3. 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

5. 4. 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

6. 5. 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
