Seismic trace is the combined function of source signal and time shifted source signal according to reflections. The complicated travel path of the propagated wave from source to detector through reflector produces time shift in the trace. If the travel paths become close together, identification of the different time shift in the seismic trace seems difficult. A method has been introduced to resolve the problem by Fourier transformation of the seismic trace and source signal used for recording. Complicated seismic traces have been implemented with different time shift and analyzed the traces by the proposed method. In every case, very good approximation is found. The technique is applied on the part of International Deep Profiling of Tibet and the Himalaya's seismic data and produces good reflection sequences. Different stratigraphy is found by the analysis.
