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.
