  1. 1. Contribution to Wideband SAR Space-Time Processing, and Radar Remote Sensing of Sea Ice

    Författare :Mats I. Pettersson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAR; clutter suppression; space time adaptive processing; backprojection; remote sensing; moving target detection; radar scattering; Antenna array; wide band; sea ice;

    Sammanfattning : Synthetic Aperture Radar (SAR) has the capability to map the Earth with high resolution and is used in both civilian and military applications. The development of SAR systems is going towards higher resolution. Today there are Wide Band (WB) SAR instruments that have a resolution actually smaller than the operating wavelength. LÄS MER

  3. 2. Extended target tracking using PHD filters

    Författare :Karl Granström; Thomas Schön; Fredrik Gustafsson; Ba-Ngu Vo; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The world in which we live is becoming more and more automated, exemplified by the numerous robots, or autonomous vehicles, that operate in air, on land, or in water. These robots perform a wide array of different tasks, ranging from the dangerous, such as underground mining, to the boring, such as vacuum cleaning. LÄS MER

  4. 3. Cost Optimization of Volumetric Surveillance for Sky Monitoring : Towards Flying Object Detection and Positioning

    Författare :Hiba Alqaysi; Mattias O'Nils; Najeem Lawal; Faisal Qureshi; Fabio Poiesi; Mittuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electronics; image processing; deep learning; YOLOv4; smart cameras;

    Sammanfattning : Unlike surface surveillance, volumetric monitoring deals with three-dimensional target space and moving objects within it. In sky monitoring, objects fly within outdoor and often remote volumes, such as wind farms and airport runways. Therefore, multiple cameras should be implemented to monitor these volumes and analyze flying activities. LÄS MER

  5. 4. Synthetic Aperture Radar Signal and Image Processing for Moving Target Indication and Side Lobe Suppression

    Författare :Thomas Sjögren; Blekinge Tekniska Högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Synthetic Aperture Radar; Space time adaptive processing;

    Sammanfattning : The thesis summarizes a selection of my research within Synthetic Aperture Radar (SAR). Mainly the research is aimed at applying and developing signal processing methods to single channel and multi channel SAR for wideband systems. SAR systems can generate images looking very similar to optical pictures, i.e. LÄS MER

  7. 5. Multi-target Tracking Using on-line Viterbi Optimisation and Stochastic Modelling

    Författare :Håkan Ardö; Matematik LTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : To study and compare the safety of intersection, traffic scientists today typically manually monitor the intersection during several days and count how often certain events such as evasive manoeuvres occur. This is a laboursome and costly procedure. LÄS MER
