Vignet-EM is a Russian low-frequency active-passive sonar station . The station includes a hardware, a launch-and-lift device and a flexible extended towed antenna (GPBA). Provides a large detection range of low-noise submarines, torpedoes.
Content
Assignment
- The armament of surface ships solving the tasks of anti-submarine defense , anti-torpedo defense , protection of water areas and specialized vessels for underwater lighting.
Tasks to be solved
- Submarine detection: in the sonar mode (GL), in the direction finding mode of discrete components and the continuous part of the spectrum;
- Far (over-the-horizon) detection of surface ships in the direction finding mode (WB);
- Detection of remote torpedoes in the direction finding mode;
- Direction finding of detected targets;
- Automated classification of targets with the participation of the operator;
- Automatic tracking;
- Measurement of acoustic noise in the work of gas
- Range prediction;
- Automated monitoring and diagnostics of GAS equipment;
