| 520 | _ | _ | |a Over the past 15 years, GPR full-waveform inversion (FWI) has shown high potential in a wide range of applications. Since most of these studies have been applied in the computationally attractive 2D environment, limitations emerge with respect to antenna modeling and wave propagation effects, consequently leading to errors in the reconstructed parameters. Here, we present recent developments for the conjugate gradient GPR FWI with a focus on a 2.5D approach, which can incorporate complex geometries, such as circular boreholes and finite-length antennas. Additionally, for high-frequency GPR applications such as related to soil columns, an enhanced model description can improve the medium reconstruction. The proposed methodology employs a 3D forward model and a 2D inversion plane, enabling the incorporation of three-dimensional structures and enhancing the precision of the results. We demonstrate the benefits of our method through three examples: typical crosshole GPR setup, variable aquifer conditions, and a lysimeter study. Our results show an improved reconstruction of the subsurface, reduced errors in crosshole GPR setups and centimeter resolution for the lysimeter study. Our study demonstrated the potential of 2.5D GPR FWI for high-resolution imaging of the critical zone, enabling improved medium characterization and a better understanding of flow and transport processes in complex subsurface environments. |
