There are many different ways that GPR users can “clean” up their data. One of the lesser known filters available is called the Deconvolution filter. This can be a powerful tool in helping remove noise, specifically “multiples” and...

What is the best way to collect a grid for GPR investigations? There are two basic ways to collect a grid: going in the same direction for each profile, or zigzagging your data collection. Obviously each of these has a benefit and a drawback. 1) Going in the same...

I was out in the Texas Oil Fields recently training some students. We were looking for flow lines… but I didn’t even know what a flow line was until I came to Texas! Flow lines are what carry out oil, gas, and water from the well and these can run in any...

There are 3 ways that relative dielectric permittivity (RDP) affects Ground Penetrating Radar waves. 1) wave velocity. RDP and wave velocity have an inverse relationship. So, if the material has a high RDP, then the waves will move slowly. 2) wavelength. GPR antenna...
