ASELSAN Intersept Sonar is ready for Turkish submarines

Submarine Intercept Sonar System developed by ASELSAN which is designed according to military requirements, has capability to detect, track and analyze active acoustic signals within 1 kHz – 100 kHz frequency range.

In 2016, ASELSAN has contracted the Ay Class Submarine Intercept Sonar tender, by competing against an international leading company. The systems will be delivered in 2017.

Submarine Intercept Sonar System consists of Intercept Sonar Acoustic Sensor Array, Processing Unit, Control and Display Unit, DC/DC Converter and SUR Interface Adaptation Units (SAUB). Acoustic Sensor Array includes pre-amplifiers, analog-digital converters (ADC) and hydrophone arrays which convert acoustic signals to electrical signal.

Submarine Intercept Sonar can be used as stand-alone system or can be integrated to  Combat Management System.

System simultaneously detects, analyzes and provides parameters of at least 4 pulses which are separable in frequency domain. The following parameters of detected pulses are displayed:

  • Detection time
  • Relative and true bearings
  • Pulse frequency
  • Pulse amplitude
  • Pulse duration
  • Pulse repetition interval (PRI)
  • Pulse mode

Submarine Intercept Sonar System displays the following graphics of detected pulses in real time:

  • Polar Diagram
  • Spectrogram Plot
  • Waterfall Plot
