Through the wall imaging(TWI) is a important technology for detection and identiﬁcation of human or other objects behind the wall especially for military and civilian applications. However, the clutter, multipath ghost, and wall distortions decrease the accuracy of current TWI-based human detection and identiﬁcation methods. Various algorithms use various techniques such as shape-based, image-based, and physicsbased techniques. In this thesis, we summarize all the techniques used for TWI and analyze the GPRbased detection techniques and evaluate their performances with simulated data. Images are obtained by simulation using gprMax software. After, the ﬂash effect removal, image segmentation and feature extraction methods are applied. Finally, obtained features are classiﬁed with SVM as targets or other objects. 108 different scenarios are generated and used in the evaluation of the algorithms.

Inside-the-wall detection of objects with low metal content using the GPR sensor: effects of different wall structures on the detection performance DOĞAN, MESUT; YESİLTURT, Omer; Sayan, Gönül (2018-04-19) Ground penetrating radar (GPR) is an ultra-wideband electromagnetic sensor used not only for subsurface sensing but also for the detection of objects which may be hidden behind a wall or inserted within the wall. Such applications of the GPR technology are used in both military and civilian operations such as mine or IED (improvised explosive device) detection, rescue missions after earthquakes and investigation of archeological sites. Detection of concealed objects with low metal content is known to be a c...
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...
Cognitive Modelling of Opposing Forces at the Simulation Analysis Lab Topcu, Yeliz; Zeyrek Bozşahin, Deniz; Ulubay, Murat; Department of Cognitive Sciences (2021-12-09) In modern military systems, engagement simulations are used to assist in conceptual design and verification of weapon systems. The quality of these simulations is directly proportional to the level of authenticity of the behavior of the components that are modeled. For this reason, it is important to represent the behavior of human controlled components by accounting for the cognitive aspects including human limitations and flaws. In various studies, the behaviors of these components are modeled using cogni...
High operating temperature mid-wave infrared HgCdTe photodiode design Yurtseven, Eray; Kocaman, Serdar; Department of Electrical and Electronics Engineering (2019) Infrared focal plane arrays are critical components in many of the military and civilian applications for advanced imaging systems. HgCdTe is one of the most widely used infrared detector material. An important issue with this material for thermal imaging system is the operating temperature as it determines cryocooler crucial characteristics, namely power comsumption and device lifetime. Therefore, there is an effort towards to operate at higher temperatures, but performance characteristics need to be caref...
Detection of Conducting and Dielectric Objects Buried under a Layer of Asphalt or Concrete Using Simulated Ground Penetrating Radar Signals DOĞAN, MESUT; GÜMÜŞ, SİNEM; Sayan, Gönül (2017-09-15) 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 ...
