Modeling of ground-penetrating radar for detecting buried objects in dispersive soils

摘要

A three-dimensional (3-D) time-domain numerical method is used for simulation of ground penetrating radar (GPR) on Debye-dispersive soil. The radar unit is modeled with two transmitters and one receiver in order to eliminate undesired signals. The impact of radar frequency, soil parameters and object depth upon the ability to detect buried targets is investigated through several FDTD simulations.
