  1. 1. Ash distribution and cavities in Icelandic glaciers, a marker for snow accumulation and radar signal velocity change

    Master-uppsats, Göteborgs universitet/Institutionen för geovetenskaper

    Författare :Andrea Håkansson; [2020-01-15]
    Nyckelord :Iceland; GPR; CMP; Glacier; Vatnajökull; Háabunga; Langjökull;

    Sammanfattning : Glaciers in the geologically active Iceland has a high scientific as well as touristic value.In this thesis, the two largest glaciers on Iceland have been studied with GPR to find ifthe method is suitable to use in future glaciolocial studies where accumulation patternsand similar attributes are in focus in a world of deglaciation.

  2. 2. Radon, radar och representationsteori

    Kandidat-uppsats, Göteborgs universitet/Institutionen för matematiska vetenskaper

    Författare :Mattias Byléhn; Rahim Nkunzimana; [2019-07-02]
    Nyckelord :;

    Sammanfattning : Detta arbete behandlar grunderna i harmonisk analys på sfären S2 och den reducerade HeisenberggruppenH1. Vi presenterar grundläggande terminologi för unitära representationer ochvisar hur man kan utvidga grundläggande koncept från Fourieranalys till sfären och Heisenberggruppen. LÄS MER

  3. 3. Assessing the accuracy for area-based tree species classification using Sentinel-1 C-band SAR data

    Master-uppsats, SLU/Dept. of Forest Resource Management

    Författare :Alberto Udali; [2019]
    Nyckelord :Sentinel-1; tree species; random forest; linear discrimi-nant analysis; classification;

    Sammanfattning : Forest type (FTY) and tree species classification (SPP) over the Remn-ingstorp test site were performed using ground-based field observations and remote sensing data sources. The field inventory for the forest estate and for the surrounding natural reserve of Eahagen was carried out in 2016. LÄS MER

  4. 4. Deinterleaving pulse trains with DBSCAN and FART

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Avdelningen för systemteknik

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

    Sammanfattning : 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. LÄS MER

  5. 5. On the statistics and practical application of the reassignment method for Gabor spectrograms

    Master-uppsats, Lunds universitet/Matematisk statistik

    Författare :Erik. M Månsson; [2019]
    Nyckelord :Mathematics and Statistics;

    Sammanfattning : The reassignment method is a technique for improving the concentration of signals in spectrograms and other time-frequency representations (TFR). It achieves this by displacing the points in a TFR according to the reassignment vector for every point. LÄS MER
