Hello. I am at the finishing stage of a academic Masters Degree. I am using GPRSoft for my reflection profile analysis. At this point in my thesis I am cross checking my time to depth and need some insight to quickly verify my depths. My adviser gave me a simple formula of VT=NS/meter with V equal to velocity and T equal to Dielectric constant of the material being scanned. With in the GPRsoft window there is a footer that denotes Amount of traces, Trace number, time, distance, depth, sample/trace and total depth. Does anyone know how these are interpreted. Any lite formula for time to depth target would be welcome but none the less any information would be great.

hi wboynton,
you should check this thread in the forum: viewtopic.php?f=29&t=726
you will find a link to a small tool to quickly calculate the required two way time (range in ns) for 1 meter depth depending on the RDP of the material.
the tool does a lot of other small calculations that may be interesting to a GPR operator.
if you would rather do the math yourself you can use a formula shown in the pic below.
