Sonar

Hull Mounted Sonar

• Medium Range - operates at approx. 6…9 kHz in active

• passive operation from 1…12kHz

• ASW active and passive operation in parallel

• automatic torpedo detection

• mine avoidance

• antenna cable is split into wet end and inboard part

• huge band width (3kHz)

• pulse length up to 4000 ms

• roll and pitch compensation

• electronic beam stabilization

• for difficult environments

• UW telephony

1m diameter Antenna

32 staves and 3 rings

2m diameter Antenna

64 staves and 3 rings

Active Towed Array Sonar

• detection of conventional submarines in

  • littoral water

  • blue water (mediteranean) in the second convergence zone

    • out of their torpedo range

• “one ping” philosophy

• optimized for littoral waters with reverberation and suppression

• depth control between 30 - 300 m of the Towed Body

• detection and tracking with high speed up to 24 kts

• survival speed up to 29 kts

• handling and operation up to see state 5

• time to operation < 1/2 hour

TASO - Towed Array Sonar + Hull Mounted Sonar

S-Kurvenfahrt um die blinden Flecken zu minimieren

• bi-static functionality

• HMS as active transmitter

• HMS and towed array (TA) as receiver

• adapted to the frequency range of the HMS

• Triplet Technology: left/right ambiguity

• automatic deployment and retrieve of TA

• 360° sensor coverage

• towed array operates below acoustic layers

• single operator, no additional worker on aft deck

Triplet array consists of

• compact components

• three Hydrophones on a pre-amplifier electronic

• left/right ambiguity

  • active / passive
