Ground Penetrating Radar

Ground Penetrating Radar (GPR) is a technology that uses electromagnetic energy in the microwave bandwidth to image objects in the subsurface.  EMC has many years of experience in both the acquisition and processing of GPR data.  With several GPR systems in-house and antenna frequencies ranging from 120 MHz to 2.5 GHz we have the right equipment to quickly get the job done.  Whether it’s locating subsurface voiding, underground utilities, structural steel/conduit in concrete or a whole host of other applications, our decades of experience allows us to interpret the results with confidence.

GPR-SLICE 3D Imaging Software

EMC utilizes Geophysical Archaeometry Laboratory’s GPR-SLICE 3D imaging software.  This world leading imaging program allows for unparalleled modeling of the GPR data.  Since GPR data are analogous to seismic data with the earliest arrivals of the reflected energy representing the shallowest of objects and later arrivals with deeper ones, this allows for 3 dimensional models and full motion animations.  In addition to the visual presentation an estimate of an anomaly’s depth can also be made.  EMC personnel regularly attend advanced training seminars to stay current with this ever advancing imaging program.
