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.

Dec 7, 2023 · Ground-Penetrating Radar (GPR) is a geophysical method that uses radar pulses to image the subsurface. It is a non-destructive technique that allows the visualization of structures and …

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 …
