Ground‐penetrating radar (GPR) is one of the best methods for detailed and high precision three‐dimensional imaging of the subsoil. A range of specific processing steps are available to correct the geometrical distortion of the georadar data. Nevertheless it is not yet possible to correct for pull‐up/pull‐down effects due to chances of velocity in target features. Unfortunately these effects can easily change the lower boundary of a structure by more than 30% of the preserved height. Hence pull‐up/pull‐down is one of the most important geometrical distortions in archaeological prospection. After a detailed three‐dimensional interpretation of the data cube, the calculation of an individual correction becomes possible and can be applied to each structure separately.
