"Sonar System Design -- A practical designer's guide offers comprehensive coverage of research on the various aspects of sonar design. It has been carefully structured to cover all areas of sonar design and serve as a guide to the designer. So…nar medium being highly complex and the sonar performance influenced by the medium, it is essential for a designer to understand the sonar medium and its influence on sonar performance. The energy source for sonar is sound and its characteristic and parameters are medium dependent; an understanding of sound propagation in sea medium is essential. The interferences in the sea are severe. For surveillance application and parameter estimation, high processing gain is essential. The spatial, spectral, and temporal characteristics of reverberation and noise are essential for designing processor to have high processing gain. All these aspects are discussed in this book. Sonar equation and its dependence on system, medium and target parameters as well as its limitation are explained to help the designer in basic design evaluation of sonar performance. Important aspects of transducer and sensors arrays to design and select a proper array are covered. Some of the important areas in sonar design are signal design, spatial and temporal processing, parameter estimation, normalisation and data fusion. The main considerations in signal design and signal processing are also covered. It includes optimum estimator, various normalisation schemes and simple linear data fusion techniques. Important applications of underwater acoustic are highlighted. Finally, the book concludes with a typical sonar design and its evaluation method.".
