Zarya-ME
Surface ship sonar system

The Zarya-ME surface ship sonar system is designed for undersea and surface targets detection to enable underwater weapon application and navigation security.

Missions:

  • submarines and surface ships detection in hydrolocation mode by hall-mounted, towed and dipping antenna arrays;
  • detection of torpedoes, submarines and surface ships in the listening mode by hall-mounted, towed and dipping antenna arrays;
  • automatic target tracking, localization and motion parameters determination, and targeting to underwater weapons;
  • objects classification into submarine, surface ship, torpedo and decoy classes;
  • torpedoes detection in the active mode;
  • hydroacoustic communications with submarines and surface ships, and identification "friend-or-foe";
  • monitoring of sonar background noise;
  • continuous automatic system’s functional testing and location.

Zarya-ME family sonars share a typical structure, differing only in array dimensions and number of hardware components on a particular ship project. Such unification is obtained thanks to the use of multiprocessor computers, standard color displays, as well as sonar management assets.

Zarya-ME sonar modifications are installed on ships of small, medium and large displacement.
