Cylindrical Array Sonar


Cylindrical Array Sonar provides a panoramic view of the sur-rounding contacts and is usually the primary sensor of a submerged submarine.


* excellent target detection performance

* excellent target discrimination, exceptionally   well maintained during target crossings

*high sophisticated automatic target detection   and tracking

* online and offline analysis for noise, pulses,   and transients

* interactive acoustical contact classification

Active Operating Sonar


Active operating sonar provides omni directional and sector transmissions with high source level (adjustable).

Variable pulse types and waveforms can be applied for active transmission, depending on the actual focus of the operation.


Intercept Detection and Ranging Sonar


With this sonar sensor, in addition to the target bearing, the target range can be estimated in the high and very high frequency band.

This gives a first indication in real-time of the target threat potential to the command.

Track data for intercept pulses is automatically associated to existing tracks from the tactical sonar sensors.

Rebounds cylindrical sensor


With intercept passive sonar any hydroacoustic pulse from sources like helicopters with dipping sonars, pinging frigates, homing torpedoes etc. can be detected and rebound over the complete frequency band.


The cylindrical sensor has a diameter of 2.4 meters and is placed on top of the tower, which means that the submarine remains undetected under all circumstances.

Forward Looking Active Sonar


The forward looking active sonar is a multi purpose sonar and provides the following functions:

* mine and obstacle avoidance

* forward looking

* bottom mapping

* bottom navigation

* surfacing protection


Doppler Log Unit

* speed over ground sensor and

   Navigation aid

Flank Array Sonar


Flank array sonar is a hull mounted sensor with optimum acous-tical decoupling from the platform providing excellent contact classification capabilities.


It is available as FAS as a line array or EFAS as a vertically ex-tended array with an increased frequency range and improved detection performance. Both variants require the same instal-lation foundation. Both arrays support target ranging capabil-ity. Optimum addition is the own noise analysis sonar ONA for monitoring own ship radiation.
