Investigations on Kinematic Refraction Inversion at Different Geological Models

In this paper a refraction inversion technique developed in the Department of Geophysics, University of Miskolc is investigated for different laterally changing geological models. It is important because the solution of the forward problem uses several approximations for significant reduction of the calculation time and these can affect the inversion results. The effects of these approximations depend on the investigated geological structure. According to our investigations it can be stated that the applied approximation gives very good results in case of slowly changing structures, while even in case of a highly changing model the inversion technique gives a result where the target model is recognizable.
