GPR uses high-frequency (usually polarized) radio waves, usually in the range 10 MHz to 2.6 GHz. A GPR transmitter and antenna emits electromagnetic energy into the ground.

Ground penetrating radar (GPR) is a non-destructive geophysical technique utilized in construction to analyze the subsurface conditions of a given site. By emitting electromagnetic pulses into the ground …

Apr 18, 2025 · Ground penetrating radar (GPR) is an electromagnetic geophysical method that transmits radio wave pulses at select center frequencies into the ground to study the subsurface.

GPR is a time scaled system which measures the time that it takes pulses of electromagnetic energy to travel from an antenna to an interface (e.g., soil horizon, bedrock, and buried feature) and back.

GPR works by detecting echoes of electromagnetic signals. First, the transmitter sends high-frequency radio waves (between 10 MHz and 2.6 GHz) into the ground. The waves pass through objects under …

Ground penetrating radar (GPR) is a non-intrusive geophysical technique that uses radar to image and survey the subsurface. It is used for a range of applications including investigating underground …
