Localized Parametric Electromagnetic Inversion for Pavement Profiling with Ground Penetrating Radar
Ground penetrating radar (GPR) has proven to be an effective non-destructive tool for pavement profiling. Layer-stripping algorithm and parametric electromagnetic (EM) inversion algorithm (referred to as EMI algorithm) are two inverse scattering approaches to estimate multilayered media properties using monostatic GPR. In this paper, a localized parametric EM inversion approach (referred to as NHD-EMI algorithm) is proposed for analyzing pavements with spatial varying characteristics. A non-homogeneous detector (NHD) is first used to divide the whole data into multiple subsegments with similar media properties. Then EMI is applied to each segment with layer-stripping technique to provide the initial model parameter estimates needed by the EMI algorithm. Numerical results show that the proposed NHD-EMI algorithm exhibits better performance over the existing EMI algorithm for nonhomogeneous pavements.
