Detection of Conducting and Dielectric Objects Buried under a Layer of Asphalt or Concrete Using Simulated Ground Penetrating Radar Signals

Sayan, Gönül
Ground-penetrating radars (GPRs) are ultra-wideband microwave sensors mainly used for detection and identification of mines and other explosive objects buried in soil or hidden under road construction layers. In this study, we investigated effects of having different construction layers over the soil surface in buried object detection problem using A-scan GPR data. A novel preprocessing technique that makes use of cumulative energy curves of A-scan signals is used for preprocessing and target detection in one easy step. Once we detect a buried object, the next step is to classify this object as either threat or clutter. Target feature extraction is essential for target classification. Simulated GPR data are analyzed in this work by quadratic time-frequency transformation techniques to obtain target features based on electromagnetic signal power distribution in joint time-frequency domain.

Down-looking Ground Penetrating Radar (GPR) is an ultra-wideband electromagnetic sensor which has important applications such as IED and landmine detection, locating people in earthquake rescue operations, detection of archeological sites, mapping ice thickness or quantification of sedimentary structures in geophysical applications. The very first and important step in target detection by GPR is the removal of ground reflections caused by the air-soil boundary as these undesired signals are usually much st...
Determination of buried circular cylinder with ground penetrating radar using an optical fiber sensor
Bulur, Hatice Gonca; Şahin, Asaf Behzat; Department of Electrical and Electronics Engineering (2011)
The terms ‘ground-probing radar’, ‘ground penetrating radar (GPR)’, ‘sub-surface radar’ or ‘surface-penetrating radar (SPR)’ refer to various techniques for detecting and imaging of subsurface objects. Among those terms GPR is preferred and used more often. In this thesis, the depth and the position of the buried circular cylinder are determined by a GPR system which comprises of an optical fiber sensor (OFS). The system is a combination of OFS, GPR and optical communication link. In order to determine the ...
Optimization of vibration characteristics of a radar antenna structure
Baran, İsmet; Özgen, Gökhan Osman; Ciğeroğlu, Ender; Department of Mechanical Engineering (2011)
Radar antenna structures especially array antennas which are integrated onto structures of aerial vehicles are subject to dynamic structural and aerodynamic loads. Due to occurrences of these dynamic loads there will be certain dynamic deformations which affect the antenna’s performance in an adverse manner. The influence of deformations and vibrations are important on array antenna structures, since they cause a change in orientation of elements of the phased array antenna which affects the gain of the ant...
Investigation of Simulated Ground Penetrating Radar Data for Buried Objects Using Quadratic Time-Frequency Transformations
DOĞAN, MESUT; Sayan, Gönül (2017-07-14)
Sub-surface sensing is a challenging area of research that highly benefits from the use of ultra-wideband ground penetrating radar (GPR) technology. Detection and classification of buried objects with reduced false alarm rates is still open to improvements. Use of joint temporal and spectral target features obtained from electromagnetic GPR signals using time-frequency representation (TFR) methods is highly promising because TFRs provide detailed information about the energy distribution of GPR signals over...
Multi-feature fusion for GPR-based landmine detection and classification
Genç, Alper; Akar, Gözde; Department of Electrical and Electronics Engineering (2019)
Ground penetrating radar (GPR) is a powerful technology for detection and identification of buried explosives especially with little or no metal content. However, subsurface clutter and soil distortions increase false alarm rates of current GPR-based landmine detection and identification methods. Most existing algorithms use shape- based, image-based and physics-based techniques. Analysis of these techniques indicates that each type of algorithms has a different perspective to solve landmine detection and i...
