In recent years, ground penetrating radar (GPR) has become an important tool for remote sensing of the earth's covers. It is known that a priori uncertainty in the electrophysical characteristics of the soil can lead to errors in determining the depth of objects during sounding. The vertical and spatial inhomogeneity of the dielectric permittivity of the soil e, as well as its frequency, seasonal and geographic dependence, lead to great difficulties in solving the GPR problem. The purpose of this work: to show the significant influence of the prior uncertainty of the dielectric permittivity and the electromagnetic model of the soil structure, i.e. vertical distribution e in depth for the error in determining the depth of objects in the ground. In a real environment, the value of the profile distribution of e is influenced not only by the composition of the substance, but also by climatic conditions, soil heterogeneity, etc. |
