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.

We test different GPR designs for ice penetration and sub-surface imaging. We determine the electrical characteristics of concrete cores for studying weathering effects and moisture retention. We ...

It also has some less known applications, such as a technology known as ground-penetrating radar (GPR). Despite the difficulty of sending and receiving radio waves through solid objects ...

The GPR is based on a wide-band, coherent, stepped frequency radar transceiver. The search head contains one transmit and two receive antennas. The transmit antenna produces continuous wave ...

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.

The updated SIR 4000 GPR control unit on display features a ... technology is compatible with both GSSI’s traditional analog antennas and newest digital offerings, resulting in the versatility ...

Ground penetrating radar detects electrical discontinuities in the shallow ... and the fully bistatic design allows for variable antenna offsets and orientations. There are a number of deployment ...
