SEISMOACOUSTIC SIGNALS PROCESSING FOR EXTENDING OF THE INFORMATIVITY OF FIBER-OPTICAL SENSITIVE ELEMENTS

The principles of recording and processing of the combination of seismic and acoustic signals from single intruder by means of the underground fiber-optical sensing element are given in this article. It shows distinctive informative features of the signals. They complement known features in terms of acoustic component. The novelty of the work is combining the processing of seismic and acoustic signals. The interferometric fiber-optical measuring network is used as distributed fiber-optical seismic acoustic sensitive element.
