GPR Interpretation

Which target is likely non-metalic?

• 1

• 2

• 3

• 4

• 5

What is the composition of the targets?

• Both metallic

• 1 is metallic and 2 is non metallic

• Can't determine

• Both non metallic

What is probably happened to the right hyperbola on line 3?

• Pipe gets deeper

• Change direction

• Local attenuation

• Pipe is broken

How do you interpret the straight signal anomaly in the middle of the line?

• Void

• Wall foundation

• External RF Interference

• GPR system error

Why is hyperbola 1 wider that hyperbola 2?

• Its bigger in diameter

• It crossed at an angle

• It contains water

• It is non-metallic

How would you interpret the anomaly pointed by the arrow?

• High attenuation

• Void

• Deterioration

• Cracking

How would you interpret the anomaly pinted by the arrow?

• Homogeneity

• High attenuation

• Void

• Low velocity
