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.

Our utility locating services employ both GPR and EM technology to provide a necessary and accurate supplement to One Call locates to provide utility mapping, and clearances for soil …

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 …

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 …

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 …

Learn how ground penetrating radar works and get your GPR questions answered by GSSI.

By emitting electromagnetic energy into the ground, GPR offers a non-invasive, high-resolution way to detect and visualize subsurface features. This guide will explore what GPR data is, how …

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 …

Ground penetrating radar (GPR) is a non-destructive geophysical method that produces a continuous cross-sectional profile or record of subsurface features, without drilling, probing, or …
