Seismic method improving signal-to-noise ratio
A method for improving signal-to-noise ratio in seismic surveying. It involves generating a series of seismic charges at time spaced intervals but at the same location. A single record is made having a time duration sufficient to cover the maximum reflection time of interest plus the total time for the series of charges. And, thereafter, the record is processed by Fourier transform of the single record to the frequency domain and by constructing frequency domain representation of the series of time intervals plus using the latter to superimpose frequency domain representations of the seismic signals resulting from each of the seismic charges. Then the processing includes inversely transforming the superimposed frequency domain representations back to the time domain.
