ON SOME PECULIARITIES OF CLUSTER ANALYSIS OF PERIODIC SIGNALS

V. Znak

Abstract

An important task of geophysical research is in the answer to the question about the quality of signals, i.e., estimating the locus of the signal and the degree of their presence in noises. Such indications determine the degree of trust to consequent estimations (e.g., estimations of wave arrival times). As seismic data are periodic signals in their nature, conventional means for examining such signals are Fourier and spectral analyses. However, this method does not allow us to clear up questions about probability of signals presence and their locus in the recorded data. We consider another approach – the cluster analysis of periodic signals, propose the formal conditions which must be satisfied by a period of signal existence, and give some results of analysis of real data recorded in field conditions.
