What is Ground Penetrating Radar?

Ground-penetrating radar (GPR) is a non-destructive geophysical method that uses radar pulses to image the subsurface.

Is there a depth range or limit to GPR?

The depth range of GPR is limited by the electrical conductivity of the ground, and the transmitting frequency. Optimal depth penetration is achieved in dry sandy soils or massive dry materials such as granite, limestone, and concrete where the depth of penetration could be up to 15 m.

Is there an area size limit?

No, there is not a limit to the size of area we can map.
