SONAR systems use sound propagation to navigate, communicate with or detect objects on or under the surface of water. If the sound pulse intercepts an object in its path, the sound bounces off the object and returns an “echo” to the sonar sub-systems.
Sonar systems are extensively used for underwater surveillance to protect ships and submarines. The acoustic frequencies used in SONARs vary from very low to extremely high. There are two types of SONAR — active and passive. Active Sonar systems emit an acoustic signal or pulse of sound into the water and analyse the echo from the objects on its path. Unlike active sonars, passive sonars do not emit its own signal, it only detects sound waves coming towards it.
Mistral has 20+ years of experience in designing SONAR Electronics and SONAR Systems for data acquisition and signal processing for applications like Diver detection, under water communications, Coastal Surveillance, CIS/CMS, etc. Mistral offers a wide array of SONAR systems and SONAR electronics subsystems, that include Towed, Hull-mounted and Dunking SONARS for underwater warfare and surveillance that meet the demanding needs of deep-sea environment. We provide Sonar subsystems for applications such as torpedo defense, manned and unmanned underwater surveillance and electronic warfare.
SONAR Subsystems Designs
Mistral provides design and development of rugged, high-performance SONAR Systems and SONAR sub-systems like underwater transducers, front-end signal conditioning units, signal processors, display systems, HMI for Optronic systems, etc. Mistral works closely with leading-edge aerospace and defense R&D companies in India and has been actively involved in design and development of indigenous SONAR Electronics for various SONAR applications deployed by the India Defense.
Mistral is certified by CEMILAC for testing and validation for defense electronics and all our SONAR systems ensure environmental compliance and EMI/EMC as per JSS55555, MIL STD 810D/G and MIL STD 461E. Our partnership with leading global organizations specializing in defense COTS like Curtiss Wright Defense and Wind River Systems enable us offer robust hardware designs and safety critical software development services. Mistral can provide custom solutions for various SONAR Systems and SONAR sub-systems like: Transmitters, Receivers, Beam Forming, Fire Control System (FCS) and Multi-function Displays. These SONAR subsystems can be implemented for multiple platforms like submarines, carriers, fighters, frigates etc. Mistral designs for underwater Defense, especially SONAR systems and subsystems are Size, Weight, and Performance (SWaP) optimized, in order to deliver a critical operational advantage in the underwater battlespace.
