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 the two-dimensional domain of time and frequency. 1 In this study, single-channel down-looking GPR data are simulated for spherical targets composed of different material contents. Following the removal of dominating ground reflections, energy distribution signatures of the A-scan GPR signals of different targets are investigated using the Wigner-Ville Distribution and Page Distribution type quadratic TFRs.

Investigation of the Effects of Buried Object Orientation in Subsurface Target Detection by GPR Doğan, Mesut; Sayan, Gönül (2017-10-27) Use of ultra-widehand ground penetrating radars (GPRs) have been the most effective approach in subsurface target detection. Proper preprocessing, prescreening, feature extraction, classification and fusion techniques are all needed to satisfy the requirements of high detection probability and low false alarm rates, simultaneously. Dominating ground reflection signals and soil clutter effects including the randomly varying non-planar ground surfaces, inhomogeneous soil nature, pebbles or rocks within the so...
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 ...
Detection and Microwave Imaging of Conducting Objects Buried Very Closely to the Air-Soil Boundary Dinc, Selman; Elibol, Hande; Guneri, Rutkay; Ozdol, Ali Bahadir; Sik, Furkan; Yesilyurt, Ismail Taylan; DOĞAN, MESUT; Sayan, Gönül (2019-01-01) 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...
Through-The-Wall Target Detection using GPR A-Scan Data: Effects of Different Wall Structures on Detection Performance DOĞAN, MESUT; Sayan, Gönül (2017-09-27) Ground penetrating radar (GPR) is an electromagnetic sensor based on the ultra-wideband radar technology that can also be used for through-the-wall (TTW) target recognition. Search for the presence of designated targets hidden behind the walls, such as stationary or moving human bodies or certain types of weapons, is addressed in various critical applications; in rescue missions after earthquakes or in military operations, etc. In such inverse problems, type of the wall is as important as the properties and...
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...
