HULL MOUNTED SONAR X2
Hull Mounted Sonar for Surface Ships is the Sonar for frigates and destroyers class of ships. The system configuration has a modular system architecture and open standard interfaces, so that variants of the system for each class of naval ship can be configured from the same basic building blocks, without having to start from scratch. The system is supplied with associated auxiliary equipment like (i) NACS, the Nearfield Acoustic Characterisation System for calibration of transducers, (ii) Sonar domes, and (iii) Directing Gears for the transducer array.
SALIENT FEATURES:
- Range: 20–30 kms
- Simultaneous detection of 4 targets
- Reduced hardware volume
- Software based design and scalable signal conditioning
- Common wideband acoustic transducer array catering to multiple requirements of active sonar and passive sonar
SUBMARINE SONAR SUITE (SMS-X)
Submarine Sonar Suite is a compendium of multiple sensors for passive detection which collates different characteristics of the same target and provides target data through information fusion. The constituent sonars in the suite include passive sonar, active sonar, intercept sonar, obstacle avoidance sonar and underwater telephony. It is designed for EKM class of submarines.
SALIENT FEATURES:
- Easily scalable to suit submarine platforms with varying levels of displacement capacity
- Contact Motion Analysis
- Automatic Torpedo Detection
- End-to-End redundancy for passive sonar systems and improved values of MTBF (Mean Time Before Failure)
ADVANCED TORPEDO DEFENCE SYSTEM FOR SHIPS WITH EXPENDABLE DECOYS
Advanced Torpedo Defence System for Ships is a fully integrated system having both torpedo detection and countermeasure capability. The system comprises of two sonars namely a hull mounted sonar and a towed array sonar for passive detection. It is a complete package involving sensors and decoys for defence against vintage as well as modern torpedoes. Acoustic decoying is effected using two types of decoys namely the towed and expendable decoys. The decoys work automatically and choose the appropriate mode of working depending on the incoming signature from the torpedo. The data from the sonar is processed in the Fire Control System (FCS).
SALIENT FEATURES:
- Acoustic decoying of the torpedo
- Classification & localisation of torpedo along with target motion parameters
- Intelligent soft kill decoy systems with multi-mode operational capability
- ECS for escape parameters
- Hydraulically operated winch system
ADVANCED LIGHT TOWED ARRAY SONAR (ALTAS-X)
ALTAS-X is variable depth, active cum passive towed array ship sonar system for detection, localization and classification of submarines and torpedoes. It provides early warning of torpedo attack. It consists of a linear towed receiver array and vertical towed projector. It is deployed into the sea with the help of robotic handling gears, on-board electronics and system software for signal processing, display & recording of sonar information.
ALTAS-X has low frequency spectrum of the radiated noise, low losses of propagation and capability to operate at different depths to make best use of the prevailing hydrological conditions.
SALIENT FEATURES:
- Capable of operations in shallow and deep waters
- Advanced adaptive beam forming techniques for detection and tracking of silent submarines
- Automatic depth keeping and bottom avoidance functions
- Minimal effect of self noise of the platform

IAC MOD ‘C’ FIRE CONTROL SYSTEM FOR TORPEDO & ROCKETS
Integrated ASW Complex MOD 'C' (IAC MOD 'C')
IAC MOD'C is a modular and fault tolerant fire control system with open system architecture and multiple redundancy for all crucial modules / sub systems of the system. It is capable to compute Contact Motion analysis (CMA) for active & passive SONAR targets and RADAR targets using state of the art tracking algorithms.
SALIENT FEATURES:
- Designation of multiple targets to attack
- Capable to generate Fire Control solution for all tracked targets within 10 sec
- Generates recommendations on own ship Course and speed to attain the weapon release point at the earliest
- Displays tracks from on-board Sonar systems and track data of on-board radars
