  1. 1. Analysis of Resistor-Loaded Bow-Tie Antennas for Ground Penetrating Radar Applications

    Author : Disala Uduwawala; KTH; []
    Keywords : Ground penetrating radar; Buried object detection; Simulation; Radar antennas; Radar signal processing; FDTD methods; Optimal design; Lossy media; Dispersive media; Clutter; Polarization;

    Abstract : Ground penetrating radar (GPR) systems are increasinglybeing used for the detection and location of buried objectswithin the upper regions of the earth's surface. Numericalsimulation of such systems plays an important role in thedevelopment of GPR hardware and signal processingtechniques. READ MORE

  2. 2. Signal Processing Techniques for Detection of Buried Landmines using Ground Penetrating Radar

    Author : Håkan Brunzell; Chalmers University of Technology; []
    Keywords : landmines; detection; feature extraction; impulse radar; ground penetrating radar; classification;

    Abstract : The present thesis deals with the problem of detecting and classifying buried objects. The application in mind when addressing this problem is the detection of buried landmines. According to the International Committee of the Red Cross, about 100 million landmines are buried in 62 countries around the world. READ MORE

  3. 3. Spatial distribution of snow in Antarctica and other glacier studies using ground-penetrating radar

    Author : Cecilia Richardson-Näslund; Robert W. Jacobel; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; GPR; ground-penetrating radar; radar soundings; snow accumulation; accumulation rate; spatial variability; Antarctica; Dronning Maud Land; cold surface layer; thermal regime; glacial cirques; Sweden; Antarktis; Glaciärer; Ackumulering av snö; Geography; Physical Geography; geografi med naturgeografisk inriktning;

    Abstract : The overall aim of this thesis is to develop and exemplify the use of ground-penetrating radar (GPR) within the field of glaciology. The main focus is on the spatial distribution of snow in Dronning Maud Land, East Antarctica. READ MORE

  4. 4. Estimation Problems in Array Signal Processing, System Identification, and Radar Imagery

    Author : Richard Abrahamsson; Peter Stoica; A. Lee Swindlehurst; Uppsala universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Parameter Estimation; Array Signal Processing; STAP; SAR; Ground Penetrating Radar; System Identification; Bilinear Models; Covariance Matrix Estimation; Signal processing; Signalbehandling; Signal Processing; Signalbehandling;

    Abstract : This thesis is concerned with parameter estimation, signal processing, and applications. In the first part, imaging using radar is considered. More specifically, two methods are presented for estimation and removal of ground-surface reflections in ground penetrating radar which otherwise hinder reliable detection of shallowly buried landmines.
