FIELD: hydroacoustics; hydroacoustic study of seas and oceans.
SUBSTANCE: proposed stationary sonar measuring system includes multi-purpose anchored lowering-and-hoisting unit with communication cable line electrically connected with surface control center by means of cable, drawing float and equipment carrier. Lower part of drawing float is connected with communication cable line; ends of coupling cable are secured to upper part of drawing float and to lower part of equipment carrier. Communication cable line is electrically connected with coupling cable by means of intermediate cable laid in inner cavity of drawing float. Ballast weights are smoothly distributed along half of coupling cable adjoining the drawing float. Total negative buoyancy of ballast weights exceeds positive buoyancy of equipment carrier by more than 20%.
EFFECT: avoidance of vibration interference effect on measurement results.
