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

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

    Sammanfattning : 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. LÄS MER

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

    Författare :Håkan Brunzell; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; landmines; detection; feature extraction; impulse radar; ground penetrating radar; classification;

    Sammanfattning : 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. LÄS MER

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