MGK-608E Passive Stationary Sonar System

MGK-608E Passive Stationary Sonar System is a group of linear phased arrays of hydrophones mounted on the sea floor at a distance from dozens to several hundreds of kilometers from the coastline.

The signals received by the hydrophones are additive combination of signal-independent noise interference of distributed long-range vessel and local source noises that are located within the system detection range. Having been filtered and amplified the signals are transformed into digital form and are transmitted to the coastal post via the fiber-optic cable channel.

MGK-608E Passive Stationary Sonar System is designed for sea surveillance in the predetermined area of responsibility. The system performs the following tasks:

  • „detection of underwater and surface objects using their hydroacoustic field parameters;
  • hydroacoustic monitoring of detected underwater and surface objects, as well as determination of their heading, speed and behaviour;
  • computer-aided object classification according to object noise emission;
  • record and archiving of detected object data;
  • computer-aided diagnostics of the technical state of MGK-608E Passive Stationary Sonar System at startup, and performance monitoring during system operation;
  • automated output of data on detected objects.

MGK-608E system includes:

1. Underwater equipment:„

  • long hydroacoustic antenna groups;
  • „signal collection and analogue-to-digital conversion equipment;
  • digital cable data links;
  • mounting kit;
  • single SPTA set.

2. Coastal-based equipment:„

  • computing system with display devices;
  • „power supply system;
  • „single SPTA set;
  • „mounting kit;
  • „user manual.
