Georadar, or Ground Penetrating Radar (GPR), is a non-destructive geophysical method that emits electromagnetic pulses to investigate or detect objects beneath the surface.
HOW DOES GPR WORK?
GPR operates by transmitting a small pulse of ultra-wideband (UWB) electromagnetic energy into the material being investigated. It then records the time taken for some or all of that energy to return, along with a measurement of the signal strength.
