Statistical evaluation of the underwater detection

Statistical evaluation of the passive structure for the vessel detection is considered. The passive detection structure is based on the statistical likelihood ratio test and on the Neyman-Pearson statistical criterion. The assumption is that a vessel is approximately so-called noisy vessel. It means that the underwater acoustic vessel noise is approximately a stationary ergodic stochastic zero mean Gaussian process with finite variance. Then the source of the vessel noise is approximately only phenomenon of the vessel propeller. The interference (ambient deep-sea noise) is a stationary ergodic stochastic zero mean Gaussian process with finite variance too.
