Direct Evaluation of a Noisy Vessel Passive Detection Structure

The paper treats direct evaluation of the statistical optimum detection of the noisy vessel in the presence of deep-sea ambient noise. The underwater noise of a noisy vessel is supposed to be an extremely weak Gaussian stochastic process that is due to vessel cavitation phenomenon. The deep-sea ambient noise is supposed to be a Gaussian stochastic process as well. The mathematical model of the power spectral density referring to the noise of the noisy vessel consists of a nonwhite wide-band component due to vessel cavitation. The mathematical model of the power spectral density referring to the deep-sea ambient noise is a nonwhite wide-band component too. The evaluation of the statistical optimum noisy vessel detection is considered in the frequency domain.
