Abstract

Improvised explosive devices (IEDs) are the Colombian version of anti-personnel mines (MAP). Like MAP, AEI hurt, maim and kill animals and people. However, AEI differ from conventional MAP because they are made of containers of varied materials, shapes and sizes. The metal detector that is currently used cannot find them all because some AEI does not have metal parts. For this reason, an alternative that has been studied in Colombia is the use of ground penetrating radar (GPR), which detects anomalies in the subsoil, sending radio signals that are reflected in the discontinuities. Thus, the performance of the GPR is influenced by the soil properties and the properties of the materials used to manufacture the AEI. Until now there has been no

characterization of these AEI, to estimate the performance of a GPR system in detecting these artifacts. In this paper we identify the dielectric constant of a selection of containers used in the manufacture of AEI, in order to estimate the performance of a GPR for AEI detection, using software to estimate its performance.
