FIELD: locating underwater objects using means alternative to sonars. SUBSTANCE: system designed for locating noiseless objects whose noise emission level is equal to or lower than sea noise level has fiber- optic temperature-fluctuation transducers disposed in sea-medium acoustic speed step layer. Transducers are capable of sensing pressure wave and underwater object trail when this object runs above fiber-optic transducers. EFFECT: enlarged functional capabilities. 5 cl, 4 dwg
