Abstract:
This paper covers the broader concept of underwater warfare, review of fundamental concepts of sound propagation in sea and detailed analysis of various sonar systems/technologies and their applications onboard various types of platforms. Sonar systems are discussed in two broad classifications of active and passive with brief mention of sonar equations. Types and role of different sonar systems onboard surface ships, submarines, aircrafts and torpedo weapon systems are discussed with Towed Array Sonar Systems presented in both active and passive configurations and Hull Mounted Sonar systems for tactical and strategic applications. Application of sonar systems in the sea as Mine Counter Measures (MCM) is also covered. Technologies contributing to the development of sonar systems are described under the concept of sonar chains and are grouped as Wet and Dry Ends. Upcoming cutting edge technologies, traditional and` novel transducer design and development including acousto-optic sensors along with their impact on the future of underwater warfare are also deliberated. Advanced processor architectures, signal processing techniques including use of FFTs and IFFTs, data processing algorithms including real time trackers, and display processors and transmitter technologies are spelled out with reference to the prototype experimentation and world wide fielded systems. The manufacturing processes applicable to the development of the Wet End are also discussed with special reference to the impact of different types of sea borne noises on the performance of sonar systems. Futuristic concept of Underwater Network Centric Warfare (UNCW) and use of Unmanned Underwater Vehicles (UUV) are also discussed for a comprehensive picture of USW. The paper is meant to introduce USW to the novice and is also a reference for those conversant with the subject.
