Is this effective against underground cables?
Does this provide response like hyperbola or gets saturated due to electric fields. Please provide clarity over this.

Well according to Peter Leach 2021 (Theory primer and guide for ACFs surveys with GPR, page 10 - and also 36) he says that air voids display a black-white-black wavelet polarity due to increase of OEM speed from soil-to-air interface. Which makes sense since the air/ground-coupled wave display always the opposite, as white-black-white, which means that the OEM went from a lower dieltric (air =1) to a higher one (average soil = 16), therefore a decrease in speed. Please let me know if I'm wrong. Cheers
