FIELD: hydroacoustics. SUBSTANCE: method is characterized by the use of additional steps compared to a known method, that is: determining a change in gleaming intensity of echo-signals from which an acoustic shape is determined, checking the correspondence of acoustic shadow shape to Carman track shape and making a decision on recognition of an object in a distance element beginning from which downstream a reducing intensity change is recorded. EFFECT: enhanced reliability in detecting objects. 1 dwg
