FIELD: radio engineering, communication.
SUBSTANCE: antenna comprises a central power element in the form of a cable, power and communication cables, sensitive elements and electronic units arranged on flexible circuit boards with a certain interval along the antenna, besides, each sensitive element is arranged in the form of a lengthy cable section with insulation from an elastic piezoelectric material, and each electronic unit is connected to the power supply cable and comprises the following serially joined components arranged on the flexible circuit board: a low noise amplifier, an analogue-to-digital converter and a unit of information preparation and transfer, besides, inputs of low noise amplifiers are connected with appropriate outputs of sensitive elements, and outputs of information preparation and transfer units are connected with a communication cable. The central power element is arranged in the form of a strong thread, a glass plastic or aramid plastic bar with a polymer coating, a circuit board with electronic units, sensitive elements, power supply and communication cables are combined into a combined device and are arranged in the form of a flat cable, and the hydroacoustic antenna as a whole is arranged in the form of a round cable.
EFFECT: invention provides for reliability of antenna operation with multiple winding and unwinding and preservation of properties of sensitive elements.
