Sažetak
The paper treats the statistical optimum passive detection of the vessels underwater noise in the presence of deep-sea ambient noise. The vessels underwater noise is supposed to be a Gaussian stochastic process composed as a sum of two statistical independent parts. One part is due to vessel cavitation phenomenon and another part is due to vessel operating machinery, mechanisms and propeller. The deep-sea ambient noise is supposed to be a Gaussian stochastic process as well. The paper considers statistical optimum detection of so sophisticated signal by means of the likelihood ratio statistical test and the Neyman-Pearson criterion. This formulation includes the statistical signal detection problem where both the signal and the noise are Gaussian stationary stochastic process with nonwhite power spectral densities. The sophisticated signal has sophisticated mathematical model of the power spectral density. It consists of a wide-band component due to vessel cavitation and of a finite number of narrow-band components due to operating machinery, mechanisms and propeller, being the sources of fundamentals tones in the vessels underwater noise. This sophisticated mathematical model of the signal power spectral density is the basis of the optimum detection algorithm synthesis. So, the statistical optimum detection is considered in the frequency domain.
