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

    University dissertation from Stockholm : Alfvénlaboratoriet

    Author : Disala Uduwawala; KTH.; [2004]
    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

    Abstract : Ground penetrating radar (GPR) systems are increasingly being used for the detection and location of buried objects within the upper regions of the earth’s surface. The antenna is the most critical component of such a system. READ MORE

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

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Richard Abrahamsson; Uppsala universitet.; Uppsala universitet.; [2006]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Parameter Estimation; Array Signal Processing; STAP; SAR; Ground Penetrating Radar; System Identification; Bilinear Models; Covariance Matrix Estimation; TECHNOLOGY Information technology Signal processing; TEKNIKVETENSKAP Informationsteknik 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.

  5. 5. Estimation of snow wetness using multi-offset ground penetrating radar towards more accurate estimates of snow water equivalent

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Nils Granlund; Luleå tekniska universitet.; [2009]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Tillämpad geofysik; Applied Geophysics; Applied Geology; Tillämpad geologi;

    Abstract : Measurements of snow water equivalent (SWE) constitute an important input to hydrological models used to predict snowmelt runoffs. The new generation of such models use distributed snow data, including distribution of SWE, as input, and rely on it for calibration and validation. READ MORE
