WebGround-penetrating radar (GPR) is a geophysical method that uses radar pulses to image the subsurface. It is a non-intrusive method of surveying the sub-surface to investigate underground utilities such as concrete, asphalt, metals, pipes, cables or masonry. This nondestructive method uses electromagnetic radiation in the microwave band (UHF/VHF …
WebThe soil surrounding an antenna or its radials has a very low resistance what entails much loss in transmission lines and buried radials. In the same time due to the soil permittivity and moisture content (water), the capacitance of any buried wire is also much higher than its value in the free space.
