Livadiya-ME
Sonar station for mines detection

Destination:

The Livadiya-ME sonar station is designed to search and liquidation support of anchored, seabed, and bottom mines.

Missions:

  • mines detection, classification and designation;
  • mines automatically localization and output data to the shipborne mine warfare management system.

Composition:

Antenna systems:

  • low-frequency underhull-mounted antenna (in a blister) for searching;
  • dual-frequency telescoping antenna for final classification;
  • hydraulic-operated and rotating machinery;
  • antenna on a self-propelled remotely controlled vehicle.

Shipborne control and data processing equipment:

  • workstation of searching operator;
  • workstation of vehicle control operator;
  • signal transmitters, receivers, and processors, control hardware, data displays;
  • integrated generator;
  • electric power units.
