development in the art of transducer design and array configuration has been spurred on mainly by two motivating forces: (1) extensive research in underwater propagation has established the advantages of increasingly lower frequencies for long-range detection and localization of targets and noise sources. (2) the advent of new piezoelectric and structural materials and of solid-state electronic devices has led to substantial improvements in transducer performance with regard to sensitivity, power output, and depth of submersion. theory has kept abreast with these developments, particularly in handling large arrays with their mutual impedance problems, in pointing to digital multipeamforming techniques, and in revealing the significance of waveform design to detection performance.
