摘要：

This article describes a numerical model of a GPR antenna used in the context of civil engineering to test structures. The model proposed was obtained by comparisons between simulations and experiments made with different cementitious materials. This model does not represent the real sensors exactly because some components are not known due in part to the manufacturing secrets, but it gives a good approach to the fields measured in the experiments.
