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 ...

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 ...

[Glenn] is building his ground penetrating radar with a bare minimum of parts. A Baofeng VHF/UHF My First Radio™ serves as the signal generator, the controller is just an optoisolator ...

The ground penetrating radar (GPR) sends radio signals into the ... there were times when all data would suddenly be lost, and the GPS signal would go down. So far, the team have been unable ...
