Product Name: Low Frequency Dunking Sonar


LFDS is an airborne sonar system which can be deployed from rotary wing platforms, for effectively acting as force multiplier for naval ships. It provides the advantages of lower frequency combined with higher source level for range advantage in littoral Anti-Submarine Warfare (ASW). It enables the deployment of sensors to deeper depths for detection of deep dived submarines. It is an integrated system capable of simultaneously processing inputs from sonobuoys and dunking sonar.

Salient Features:

  • Sonar and Sonics modes of operation
  • Light in weight for fitment on light and multi-role helicopters
  • Foldable array for higher acoustic aperture
  • Spectral analysis of the tracked targets
  • Low frequency of operation for extended ranges
  • Echo-sounding for bottom proximity
  • Comprehensive in-built test facility for online health monitoring
  • Integrated sonar performance prediction
  • Microprocessor controlled winch system with safety interlocks
  • Spectral analysis of the tracked targets
  • Low frequency of operation for extended ranges
  • User-friendly Human Machine Interface

Application of the Product:

The system uses the latest technologies and employs well-proven algorithms, which enable the in sonification of relatively long ranges with the required resolutions, to adequately meet present day ASW requirements.

Status of the product:

User evaluation under progress
