Figure 29: GP app software image processing background removal
Use with caution, background removal may remove desired targets.
When first viewing a GPR radargram (B Scan), it is advisable to set background removal
to zero so as not to remove legitimate linear features from the data.

5.6.4 Dielectric constant
The concrete material characterized by the dielectric ε (permittivity) influences hugely the
measurement.
- When concrete is dry (ε<5), GPR waves are less attenuated and can penetrate deeper
resulting in more prominent signals/hyperbolas.
- When concrete is wet (ε>9), GPR waves are heavily attenuated by the presence of
water resulting in less prominent signals/hyperbolas.
The standard concrete usually has a dielectric (ε) between 6.5 and 7.5.
