  1. Ground-penetrating radar - Wikipedia

    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.

  2. Ground Penetrating Radar (GPR) - US EPA

    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.

  3. Ground-Penetrating Radar (GPR) - Geology Science

    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 …

  4. GPR Explained - What is Ground Penetrating Radar? | GPRS

    Ground penetrating radar (GPR) is a non-destructive detection and imaging method which identifies subsurface elements either underground or within a surface such as concrete. …

  5. Understanding GPR Data: A Guide to Ground Penetrating Radar …

    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 …

  6. What is Ground Penetrating Radar?

    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 …

  7. Ground Penetrating Radar (GPR): What is it & How it Works?

    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 …

  8. Ground Penetrating Radar - CLU-IN

    Ground penetrating radar (GPR) is a shallow, high-resolution geophysical method that uses high-frequency, pulsed, electromagnetic waves to image the subsurface.

  9. Ground-Penetrating Radar | Environmental Geophysics | US EPA

    Ground-penetrating radar (GPR) uses a high-frequency (e.g. 40 to 1,500 MHz) EM pulse transmitted from a radar antenna to probe the earth. The transmitted radar pulses are reflected …

  10. Ground Penetrating Radar – GPR | Guideline Geo

    A Ground Penetrating Radar, also known as a GPR, Georadar or sometimes even Ground Probing Radar, is a non-destructive and rapid geophysical method that operates by …
