We verify the characterization of the subsoil in order to identify the presence of buried foreign bodies (anomalies) due to shape and size to war devices.The radar reflection technique allows us to identify the presence of variation of the dielectric constant of the investigated medium: these variations manifest themselves as organized reflections of the impulsive radar signal and can be originated, for example, by lithological changes, interfaces between materials with different characteristics , structural discontinuities, cavities, reinforcement rods, metal objects and buried structures.
