Abstract

The quantified interpretation of the seismic refraction record depends on correct and feasible picking first arrival times. However, if the refraction data include much environmental noises, the current first arrival picking techniques are not enough. For this reason, novel techniques are necessary to obtain first arrival times from such data. In this study the cross-correlation process which is an important step in reflection data processing was used in investigating of the first arrival time picking on seismic refraction data. By means of the technique, the process of the first arrival time picking is realized as quasi-independent, erroneous picking to be arise from environmental noises was decreased and picking procedure was attributed to mathematical base
