GPR Signal Strength

Can I tell what type of target I have by the GPR signal strength?

GPR signal strength is survey dependent and the simple answer is no.  This is because the same object can give different signal responses depending on different factors. GPR signal strength or amplitude is not specific to just a type of target. Signal strength is based on several factors: electrical contrast, object size/orientation, and signal absorption (subsurface conditions). The electrical contrast between materials …
