1. 11. Representation Learning for Modulation Recognition of LPI Radar Signals Through Clustering

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

   Author : Mila Grancharova; [2020]
   Keywords : Clustering; Representation Learning; Semi-Supervised Learning; Low Probability of Intercept Radar; Automatic Modulation Recognition; Klustring; semiövervakad inlärning; representationsinlärning; Low Probability of Intercept radar; automatiserad modulationsigenkänning;

   Abstract : Today, there is a demand for reliable ways to perform automatic modulation recognition of Low Probability of Intercept (LPI) radar signals, not least in the defense industry. This study explores the possibility of performing automatic modulation recognition on these signals through clustering and more specifically how to learn representations of input signals for this task.

3. 12. Noise Robustness of Convolutional Autoencoders and Neural Networks for LPI Radar Classification

   University essay from KTH/Matematisk statistik

   Author : Gustav Norén; [2020]
   Keywords : LPI radar; CNN; autoencoder; noise robustness; denoising; LPI radar; CNN; autoencoder; brustålighet; avbrusning;

   Abstract : This study evaluates noise robustness of convolutional autoencoders and neural networks for classification of Low Probability of Intercept (LPI) radar modulation type. Specifically, a number of different neural network architectures are tested in four different synthetic noise environments. READ MORE

4. 13. Finding the most suitable auxiliary sonar for terrain-aided navigation and behavior-fusion based obstacle avoidance for an autonomous underwater vehicle

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : NILAS OSTERMAN; [2019]
   Keywords : ;

   Abstract : Autonomous underwater vehicles are rapidly becoming more common and developed for both military as well as civilian applications such as; mine countermeasures or in the field of geoscience. One of the main issues these vehicles are facing today is the navigation capability. READ MORE

5. 14. 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

6. 15. Fast filtering of mobile signals in radar warning receiver systems using machine learning

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

   Author : Jorge Andres Munoz Caceres; [2018]
   Keywords : machine learning; radar warning receiver; deep learning;

   Abstract : The radio frequency spectrum is becoming increasingly crowded and research efforts are being made both from the side of communication and from radar to allow for sharing of the radio frequency spectrum. In this thesis, suitable methods for classifying incoming signals as either communication signals or radar signals using machine learning are evaluated, with the purpose of filtering communication signals in radar warning receiver systems.
