  2. 1. Ground Object Recognition using Laser Radar Data : Geometric Fitting, Performance Analysis, and Applications

    Author : Christna Grönwall; Fredrik Gustafsson; Kalle Åström; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Laser radar; object detection; object recognition; performance; least squares; ICP; Cramér-Rao; Signal processing; Signalbehandling;

    Abstract : This thesis concerns detection and recognition of ground object using data from laser radar systems. Typical ground objects are vehicles and land mines. For these objects, the orientation and articulation are unknown. The objects are placed in natural or urban areas where the background is unstructured and complex. READ MORE

  4. 2. 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

    Author : Clas Veibäck; Gustaf Hendeby; Fredrik Gustafsson; Hans Driessen; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Target Tracking; Sensor Fusion; Motion Models; Animals; Cameras; Radar;

    Abstract : Target tracking is a mature topic with over half a century of mainly military and aviation research. The field has lately expanded into a range of civilian applications due to the development of cheap sensors and improved computational power. READ MORE

  6. 4. Factorized Geometrical Autofocus for Synthetic Aperture Radar Processing

    Author : Jan Torgrimsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Back-Projection; PGA; SAR; UWB; Autofocus; FGA;

    Abstract : Synthetic Aperture Radar (SAR) imagery is a very useful resource for the civilian remote sensingcommunity and for the military. This however presumes that images are focused. There are severalpossible sources for defocusing effects. For airborne SAR, motion measurement errors is the maincause. READ MORE

  7. 5. Signal Design for Active Sensing and Communications

    Author : Mojtaba Soltanalian; Petre Stoica; Bo Wahlberg; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Man-made active sensing systems such as active radar and sonar have been a vital part of our civilization's advancement in navigation, defense, meteorology, and space exploration. Modern active sensing systems rely heavily on the significant progress in the science and technology of communications made within the last century. READ MORE
