  2. 11. Development and evaluation of SAR algorithms for image formation and speed estimation in wideband SAR

    Author : Thomas Sjögren; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Remote sensing and surveillance are the main application areas for radar in general and synthetic aperture (SAR) radar in particular. Since the first radar system built by Hülsmeyer in 1904, radar has developed so that it is now able to create images from a large distance. READ MORE

  4. 12. Integrated Sensing and Communication in Cell-Free Massive MIMO

    Author : Zinat Behdad; Cicek Cavdar; Ki Won Sung; Özlem Tugfe Demir; Huseyin Arslan; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Integrated sensing and communication; cell-free massive MIMO; power allocation; URLLC; C-RAN; convex-concave programming.; Integrerad avkänning och kommunikation; cellfri massiv MI- MO; effektallokering; URLLC; C-RAN; konvex-konkav programmering;

    Abstract : Future mobile networks are anticipated to not only enhance communication performance but also facilitate new sensing-based applications. This highlights the essential role of integrated sensing and communication (ISAC) in sixth-generation (6G) and beyond mobile networks. READ MORE

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

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

    Abstract : 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. READ MORE

  6. 14. Robust Visual Object Tracking mean shift, particle filters and point features

    Author : Zulfiqar Hasan Khan; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; PF; MSEPF; mean shift; visual object tracking; RANSAC; SIFT; SURF;

    Abstract : Visual object tracking has been identified as a promising technique for many computer vision applications like surveillance, flight navigation, video compression and driver assistance. The main idea is to find the state ofthe object and how it changes over time, in recursive video frames. READ MORE

  7. 15. Visual Analysis of Multidimensional Data for Biomechanics and HCI

    Author : Gregorio Palmas; Tino Weinkauf; Silvia Miksch; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Computer Science; Datalogi;

    Abstract : Multidimensional analysis is performed in many scientific fields.Its main tasks involve the identification of correlations between data dimensions,the investigation of data clusters, and the identification of outliers. Visualization techniques often help in getting a better understanding. READ MORE
