Full-waveform inversion of GPR data has shown a high potential in many applications to obtain accurate and quantitative high resolution images of the subsurface. We implemented a new full-waveform inversion that combines an accurate 3D forward modeling approach with a shuffled complex evolution method that incorporates the complicated wave interactions and interferences that cannot be resolved by...
This study presents the findings of a GPR investigation at two archaeological sites in Vadnagar, India; Area 1: Gaon Tal near a Hindu Temple (23°47'19.57″N; 72°38'47.75″E) and Area 2: Baba No Tekdo locality II (23°47'30.53″N; 72°38'55.59″E). Area 1 was surveyed in two plots of dimensions 16m × 10m and 12m × 16m, and Area 2 in a single plot of size 40m × 36m. Total seventy-two profiles were taken using...
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...
