FIELD: hydroacoustics. SUBSTANCE: method consists in detecting periodic signals of noise radiation of oscillating system which consists of oscillating body (moored mine body) and vortex streets. Then mutually correlated function between received signal and standard periodic signal at frequency ω is calculated. Decision on identification of moored mine of definite type is taken in case of coincidence of period of undamped mutually-correlated function at period t of natural oscillations of moored mine in stream. EFFECT: enhanced reliability of identification at retained security from observation due to employment of passive method of identification of moored mine. 1 dwg
