FIELD: hydroacoustics.
SUBSTANCE: invention relates to hydroacoustics and can be used to detect a moving sound source and measure its coordinates in a shallow sea in a passive mode using acoustic combined receivers installed on the seabed, whose coordinates and angular position are considered known. The application describes the design of a hydroacoustic complex, including a block system for collecting, processing and displaying information.
EFFECT: invention makes it possible not only to detect a noisy underwater object, but also to determine its coordinates in a passive mode.
