The invention relates to sonar technology and can be used in autonomous anchor sonar station of the systems for protection of underwater space for detection and direction finding by a vector phase processing of submarines, tsunami waves, for seismic prospecting. An autonomous sonar buoy anchor station comprises an underwater sonar buoy with instrumental compartment and ballast interconnected by supports with a sonar antenna attached to them. The sonar buoy is connected by a buoy rope to the anchor. The radio buoys with triggering devices are located in the containers that are attached to the instrumental compartment. The essence of the invention lies in the fact that the sonar antenna is designed as a combined vector-phase antenna with a movable body, which three component parts are connected by flexible joints (e.g., cords). The upper part of antenna in the form of a disk is rigidly connected to the supports of sonar buoys, the central and lower parts of antenna body are movable. The central part of antenna body is designed as a ring, around the perimeter of which receivers of acoustic wave pressure are located, for example, 4 pieces, in the center of the ring on flexible fastening elements a vector receiver of sonar waves is mounted in the form of a spherical shell. Electrodynamic sensors are mounted inside the spherical shell on the lodgment in pairs symmetrically to the center along three mutually perpendicular axes in a Cartesian coordinate system 0, X, Y, Z. The body of each electrodynamic sensor has two-sided hinged supports located above the center of gravity of the sensor and connected to the sphere lodgment. The lower part of antenna body is made in the form of a disk and serves as a movable counterweight. The technical result of the invention consists in improving reliability, efficiency and performance of the sonar buoy anchor station due to the fact that the sonar antenna is designed as a combined vector-phase antenna with a movable body, which structural elements leads to increase of all above mentioned indicators. |
