The GPR method has increasingly found application in non-destructive testing of reinforced concrete structures. This paper presents the new approach of modelling of the electromagnetic wave propagation for reinforced concrete structures with a complex system of reinforcement. Simulations of the GPR field were performed on a three-dimensional model of a footbridge using the FDTD method. Numerical maps...
In this paper we cope with the problem of the evaluation of the propagation velocity of the electromagnetic waves in the soil from diffraction hyperbolas. In particular, some limits of the well known method of the diffraction hyperbolas are put into evidence and are partially overcome by means of a sequential migration algorithm, which provides a fast, easy, and reliable technique, not requiring separable...
