Radar is a useful tool with familiar uses such as detecting aircraft and observing weather. It also has some less known applications, such as a technology known as ground-penetrating radar (GPR).

One of the most interesting is [Glenn Powers]’ Open Ground Penetrating Radar. It’s exactly what the title says: an open-source radar system that can see into the Earth for less than $500.

Ground penetrating radar detects electrical discontinuities in the shallow subsurface (<50m) by generating pulses of high-frequency electromagnetic energy and detecting the reflections from the ...

We found LOST graves using GPR! (Ground Penetrating Radar) the church dated to the American Revolution and was burned by the British near Charleston, SC. We are flagging graves found during our search ...

Antennas used with ground penetrating radar (GPR) come in different shapes and sizes. The largest antennas typically radiate the lower frequencies necessary to detect the deepest targets.
