Abstract

Abstract

Based on the governing equations satisfied by the electromagnetic method of the frequency domain, the finite element method is used to realize the forward simulation of 2.5-Dimensional a (2.5D) Ground Penetrating Radar (GPR) in the frequency domain. The law of the electromagnetic field spectrum in the wavenumber domain with the relative permittivity and the transmission and reception distance is analyzed in detail. The selection of the wave number in the 2.5D GPR forward modeling simulation is discussed. Based on the comparison of the computational efficiency of the Open MP parallel algorithm and the serial algorithm, the results show that the 2.5D GPR numerical simulation method in the frequency domain has the characteristics of high efficiency, high precision, and high parallelism. It provides important theoretical reference and technical support for radar forward modeling, and provides an important foundation for GPR full waveform inversion.
