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 identification problem. Therefore, one type of method has stronger and weaker points with respect to the other types of algorithms. To reduce false alarm rates of the current GPR-based landmine detection and identification methods, this study proposes a combined feature utilizing both physics- based and image-based techniques. Combined features are classified with support vector machine (SVM) classifier. The proposed algorithm is tested on a simulated data set contained more than 400 innocuous object signatures and 300 landmine signatures, over half of which are completely nonmetal. The results presented indicate that the proposed method in this study has significant performance benefits for landmine detection and identification in GPR data even in cluttered environment.

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...
Multi-Aspect Data Fusion Applied to Electromagnetic Target Classification using Enetic Algorithm
Sayan, Gönül (Kluwer Academic Publishers, 2002-01-01)
Electromagnetic target detection and classification is an important problem relevant not only to military applications but also to civilian use. In the problem of a breast tumor detection and identification [1], for instance, the main concern is accuracy. In the case of the recognition of a military target such as an aircraft or a ship, on the other hand, speed of classification is as important as the accuracy of the decision as such a decision should be made within a fraction of a second. For...

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 ...
