SONAR systems use sound propagation (Ultrasonic waves) to navigate, communicate with or detect and locate objects on or under the surface of the water. When the sound pulse intercepts an object in its path, it bounces off the object and returns an “echo” to the sonar sub-systems, which receive and process the data to determine the range and orientation of the object. SONAR Subsystems are an active component used used for diverse underwater surveillance purposes such as torpedo defense, electronic warfare, and unmanned surveillance.

SONAR Systems

Sonar systems are extensively used for underwater surveillance to protect ships and submarines by detecting enemy torpedoes and subsea vehicles. The acoustic frequencies used in SONAR systems vary from very low to extremely high frequency. There are two types of SONARS – active and passive. Active Sonar systems emit an acoustic signal or pulse of sound into the water and analyze the echo from the objects on its path. Passive SONAR, on the other hand, only detects sound waves coming in its direction.

Mistral has over 25 years of experience in designing SONAR Electronics and SONAR Systems for data acquisition and signal processing for applications like diver detection, underwater communications, coastal surveillance, CIS/CMS, synthetic aperture SONAR, surveillance SONAR, towed array depth sonar, twin inverted pulse SONAR and advanced sonobuoys among others. We provide Sonar subsystems for applications such as torpedo defense, manned and unmanned underwater surveillance and electronic warfare. Mistral also offers a wide array of SONAR systems and SONAR electronics subsystems, including Towed, Hull-mounted and Dunking SONARS for underwater warfare and surveillance that meet the demanding needs of the deep-sea environment.

SONAR Subsystems Design

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 and SONAR Subsystems for various applications deployed by the Indian Defense Forces.

Mistral is a CEMILAC certified Research and Development Centre for testing and validation of defense electronics and all our SONAR systems conform to various environmental compliance and EMI/EMC as per JSS55555, MIL STD 810D/G and MIL STD 461E. Our partnership with leading global organizations like Curtiss Wright Defense and Wind River Systems specialized in defense COTS Hardware and Software Products enable us to offer robust hardware designs and safety critical software.

Mistral provides custom solutions and engineering services for various SONAR Systems and SONAR sub-systems such as 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.
