•Uncertainty of depth surveyed by ground penetrating radar is modelled and evaluated.•Evaluated uncertainty is not strongly dependent to the burial depth of the target.•Scattering noise in the radargram dominates the evaluation of uncertainty.•The 95% confidence interval is ±11.5% of estimated depth...
