Modernised sonar system for submarines

Destination

The MGK-400EM modernised sonar system is designed for surveillance underwater and surface sea situation to enable actions and weapon application of a submerged submarine.

Мission

The MGK-400EM sonar system can be installed on nonnuclear submarines and to perform the following missions:

  • search, detection and taking bearing to submarines, surface ships and torpedoes by their noise emission;
  • automatic target tracking;
  • intercept of sonar signals transmitted from submarines, surface ships and torpedoes;
  • detection, localization of the target and distance measuring in active sonar mode;
  • mine search and detection of navigation obstacles;
  • automatic target classification and targeting to underwater weapons;
  • underwater communication in low frequency band, high-frequency band communication, identification “friend-or-foe” and measuring of the distance (MD) to correspondent;
  • monitoring of sonar background noise;
  • prediction of sonar operation range;
  • automatic testing and troubleshooting of sonar system.

MGK-400EM sonar system features advanced antennas with new piezoelectric ceramic compounds and electro acoustic transducers of improved design.
