Abstract
COMSOL Multiphysics is one of the most popular multi-physics numerical calculation software. The forward modeling of GPR is realized based on COMSOL RF module, and the layered strata are simulated and verified by using Rake wavelet with center frequency of 400 MHz. The results show that the numerical simulation method of GPR established by COMSOL RF module has high calculation accuracy, which is helpful to study the propagation law of electromagnetic waves.
