Ground-Penetrating Radar (GPR)

Ground-penetrating radar is a technology that uses pulses of electromagnetic radiation to penetrate the surface of the ground, and go below to reveal any anomalies in soil or other materials. Ground-penetrating radar uses microwave band frequencies, generally from 10 MHz to 1 GHz.

Ground-penetrating radar machines are often designed to be portable, with connections to a traditional laptop or other interface technologies, and memory systems built in. They typically run off of batteries. These machines conduct pulses over an area that are collectively called a “scan.” The antenna sends a signal into the ground and returns signals based on what is underneath the surface. Ground-penetrating radar is used for things like geological profiling, and to determine the placement of objects of different types in underground areas.
