  1. 1. 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

  2. 2. 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

  3. 3. Propagation of Radio Waves in a Realistic Environment using a Parabolic Equation Approach

    University essay from Linköpings universitet/Teoretisk Fysik

    Author : Jonas Ehn; [2019]
    Keywords : Electromagnetic fields; wave propagation; radar; parabolic equation; split-step Fourier method;

    Abstract : Radars are used for range estimation of distant objects. They operate on the principle of sending electromagnetic pulses that are reflected off a target. This leads to the propagation of electromagnetic waves over large distances. As the waves propagate, they are affected by several aspects that decrease the performance of the radar system. READ MORE

  4. 4. Road modelling using LiDAR-data

    University essay from Lunds universitet/Matematisk statistik

    Author : Tove Jungenfelt; Elias Sevelin; [2018]
    Keywords : Mathematics and Statistics;

    Abstract : The purpose of our master thesis is to locate and find a mathematical model of the road surface from data obtained using LiDAR measure- ments. A LiDAR is an optical instrument that generates a point cloud of its surroundings by measuring distance and intensity. READ MORE

  5. 5. Compressed Sensing for 3D Laser Radar

    University essay from Linköpings universitet/DatorseendeLinköpings universitet/Tekniska högskolan

    Author : Erik Fall; [2014]
    Keywords : compressed sensing; compressed sampling; TCSPC; TV minimization; l1 minimization; DMD;

    Abstract : High resolution 3D images are of high interest in military operations, where data can be used to classify and identify targets. The Swedish defence research agency (FOI) is interested in the latest research and technologies in this area. A draw- back with normal 3D-laser systems are the lack of high resolution for long range measurements. READ MORE
