DEVICE FOR DETECTING AND LOCATING A WATER ENTRY IN AN UNDER-WATER ACOUSTICAL ANTENNA

摘要

A device for detecting water penetration into a marine acoustic streamer with segments interconnected by connectors. Each connector positioned between any two adjacent segments is provided with sensors which are constituted by flexible printed circuits having two distinct and interleaved conductive combs thereon. A bifilar line interconnects the sensors, and an emitting and receiving circuit allows a sensor whose impedance has been changed by the infiltration of water into the connector to be located by means of a reflectrometric method, whereby the operating condition of such marine acoustic streamer can be supervised efficiently and at low cost.
