6.7.4 Gain
Since the material being scanned absorbs the GPR signal, deeper targets return weaker
signals. Gain acts like an audio volume control, amplifying signals and making deeper targets
appear stronger in the image. Gain values vary from 1 to 9 where 1 means a minimal
amplification has been applied and 9 means that maximum amplification has been applied.
Pressing this button increments the gain; once you reach 9 it cycles back to 1. Avoid over-
gaining the data as it can make interpretation difficult (Figure 6-16). In general, soils that are
more electrically conductive (e.g. clays) will require a higher gain compared to soils that are less
electrically conductive (e.g. sand).
