Chan K. Research of probability perfprmances of acoustic fluctuation signals

Thesis is devoted to deveplopment suitable for engineering application of a mathematical means of abalysis of the law of distribution of non-Gaussian nonstationary signals. For research the law of distribution of acoustic fluctuation signals the method spectral function of the shoccks is justified. The common formula of spectral function of the shocks of linear casual processes wutn the inhomogeneous father process is obtained. Are calculated spectral function of the shocksof standard models of acoustic fluctuation signals. The evaluation of charactericstic function and spectral function of the shocks is obtained. The mathematical model of signals acoustic emission is justified. The formula for cumulant function, spectral function of the shocks and the law of distribution of signal acoustic emission are obtained.
