Ground penetrating radar (GPR) uses radio waves to detect buried objects in any non-metallic material.
Initially used to detect structures in ice, GPR has evolved to include the penetration of soils, rocks and man-made structures.
GPR is used to map the interior of any object penetrable by radio waves, just as X-rays image the internal structure of
the body. GPR uses a sensitive detector to record weak radio waves reflected from objects embedded in the material under investigation.
Measurements must be made at many points to ensure accurate representation of the area being examined.
A computer records and merges the GPR data to create an image. Hyperbola (arches) displayed on this
image
indicate the placement and depth of objects in the survey area.
The depth of exploration and image definition depend on the radio frequency used. Low frequencies are used for deep geological mapping,
while high frequencies are necessary for high definition imaging, such as delineating reinforcing bars in concrete.
Sensors & Software's pulseEKKO systems offer a wide range of frequencies to accommodate numerous applications.
