Thesis Abstract

Abstract
Ground Penetrating Radar (GPR) is a non-invasive geophysical technique that has gained significant popularity in subsurface imaging applications, particularly in urban environments. This thesis investigates the use of GPR for subsurface imaging in urban settings, focusing on its effectiveness, limitations, and potential for enhancing underground utility mapping and infrastructure assessments. The research methodology involves a combination of field surveys, data processing, and analysis to evaluate the performance of GPR in various urban scenarios. The introduction provides an overview of the significance of subsurface imaging in urban environments, highlighting the challenges faced in traditional methods and the potential benefits of using GPR. The background of the study delves into the principles of GPR technology, its applications, and previous research in the field. The problem statement identifies the gaps in current subsurface imaging techniques and sets the foundation for the research objectives. The objectives of the study include assessing the accuracy and resolution of GPR in urban environments, investigating the challenges and limitations of GPR technology, defining the scope of applications for GPR in urban subsurface imaging, and determining the significance of GPR for improving underground utility mapping and infrastructure assessments.
