Ground Penetrating Radar (GPR)
The Ground Penetrating Radar instrument consists of a recorder and a transmitting and receiving antenna, with different antennae being used to provide different frequencies. The transmitter provides high-frequency electromagnetic signals that penetrate the ground and are reflected from objects and boundaries that have a different dielectric constant from their host material. GPR has a wide variety of applications, from locating rebar and post-tension cables within concrete, to subsurface void and underground storage tank detection, to mapping bathymetry under ice-covered lakes. ZAPATA conducts high-resolution GPR surveys for all of these applications.
