Ground Penetrating Radar Numerical Modeling for Disease Detection Using COMSOL
As a non-destructive testing (NDT) technique for disease detecting in pavements, ground penetrating radar (GPR) has garnered increasing attention. However, it is still a problem to determine which kind of disease is easy to detect. This paper investigates the utilization of the finite element method (FEM) software COMSOL to model the propagation of electromagnetic waves in pavements. Two quantities of interest were investigated and analyzed numerically: depth and radius. The amplitude is used to determine the complexity of finding the disease. The result is that the disease with larger radius and lower depth can be recognized easily.
