A Homogenous Prototype Design for IED Detection Using Subsurface Ground-Penetrating RADAR

Security is a prime factor of a nation’s peace. Nowadays, terrorists are using Improvised Explosive Devices for their attacks. This paper presents a method to locate, characterize, and identify the IED in landmines using a subsurface technology called Ground-Penetrating RADAR with electromagnetic imaging. By this technique, the homogenous nature of soil, moisture content, dielectric constants of air, soil, and explosives are analyzed. To measure the attenuation and scattering losses of IED underground, a homogenous 2D prototype model is designed with TNT explosives as IED. By simulation, the scattering loss and attenuation are characterized over the step frequency range from 0.5 to 3 GHz. The step frequency shows that the optimal frequency to detect IED in the subsurface scan was 2 GHz. Based on the experimental results, the interference is more in dry soil than wet soil and also the dimension of landmine is directly proportional to the amount of scattering.
