Abstract: Interferometric processing of hydroacoustic information by using a horizontal linear antenna is described. The detection of a noise source signal is considered by using the Neumann-Pearson criterion. The expressions for the probability of correct detection and false alarm are obtained as dependence on the signal/noise (s/n) ratio and the number of antenna elements. Numerical calculations are performed. The curves of the probability of noise signal detection are given. The efficiency of signal detection by using an antenna in relation to a single receiver is estimated.

Keywords: dispersion, interferometry, noise source, Neumann-Pearson criterion, detection characteristics, horizontal antenna, modeling
