- •
Ground penetrating radar is an increasingly used non-destructive testing technology.
- •
Few international GPR standards exist with inhomogeneous recommendations.
- •
A detailed analysis of the system performance is lacking in the standards.
- •
We propose a GPR signal processing to evaluate precision and bias of test methods.
- •
We analyze the relationship between GPR frequencies, thresholds, and signal accuracy.
