Product Name: ALTAS-X


ALTAS-X is a variable depth surface-ship sonar system for detection, localisation and classification of silent submarines in active and passive modes. As an advanced underwater sensor system, it provides early warning of torpedo attack, thereby strengthening the Anti-Submarine Warfare (ASW) capabilities of advanced warships. ALTAS-X has the distinct advantage of having a long array to exploit the low frequency spectrum of the radiated noise, low losses of propagation, capability to operate at different depths to make best use of the prevailing hydrological conditions and minimal effect of self-noise of the platform.

Salient Features:

  • Active cum passive towed array sonar capable of detection, localisation and classification of submarines and torpedoes
  • Low frequency variable depth sonar capable of operations in shallow and deep oceans
  • Advanced adaptive beam forming techniques for detection and tracking of silent submarines
  • Operator selectable transmit wave-forms, pulse lengths, bandwidths and range scales
  • Adaptive noise cancellation and own Doppler nullification techniques
  • Advanced signal processing techniques for broadband and narrowband functions
  • Real time data recording for online/offline processing
  • Automatic depth-keeping & bottom-avoidance functions
