This notebook contains two apps, which are used to complete part 3 in GPR Lab 6:
By using the models provided (pipe/slab) to fit data signatures within field collected radargram data, we can determine the existence, location and dimensions of pipes and slabs. You may also use this app to learn how radargram signatures from pipes and rectangular slabs change as the parameters provided are altered.

In the context of the lab exercise (Interpretation of Field Data), it is known that several pipes are likely buried below the GPR acquisition line. Unfortunately, we do no know the location or dimensions of the pipes. Here, you will attempt to fit radargram signatures corresponding to pipe-shaped objects. Parameters which provide the best fit can be used to infer characteristics of buried pipes.

In the context of the lab exercise (Interpretation of Field Data), it is known that a concrete casing is buried below the GPR acquisition line. Unfortunately, we do no know the location or depth of the casing. Here, you will attempt to fit radargram signatures corresponding to the casing using a rectangular slab model. Parameters which provide the best fit can be used to infer information about the casing.
