In order to find small scale inclusions, in particular aircraft bombs and mines in the underground, GPR measurements are used more and more. Especially in the range of the localization of bombs, different from mine search, hardly any scientific reports can be found. In the context of this diploma thesis was attached importance to the localisation of bombs. For this purpose the effect of changing the parameters of the host sediments porosity, water saturation and clay content on the permittivity was determined and calculated. Subsequently this data was used to form the properties of the geological model for the simulations. The resultant synthetic radargrams were provided with the simulation software GPRSIM. The dimension of the buried object in the model corresponds in shape and size a 250 kg bomb from the second world war. The modelling was done for different angles of incidence. Furthermore it was differentiated between a homogeneous subsurface and a layered subsurface with some other small compounds in addition. Finally over a suspicion surface measurements were accomplished with different frequencies. Additional a bomb was buried in the subsurface to be able to compare this data with the synthetic radargrams.
