Examples of Radar Profiles

Profile to the left is of a flat concrete slab. A local construction
company wanted to know what if any re-bar or other re-inforcing materials
were used within the slab. It became immediately obvious using the
radar system with a 250 MHz antenna that "metal decking", delineated by
a yellow line was embedded within the slab. The red line shows the
bottom of the concrete slab. The numbers on the top indicate the length
of the profile in linear feet. The instrument used was the Sensors
and Software "Noggin" system. This is an excellent system for a wide
variety of Radar Applications. They were also looking for any
pipes or other conduits within the slab. These were also found
and marked to be avoided by the construction crews, during cutting of the
concrete slab. GPR can be a very important tool for construction
and a wide variety of other shallow geophyscial applications.
