Introduction to acoustic signal processing

Abstract

Acoustic Signal processing is a short course in electrical signal processing fundamentals and their applications in the field of underwater acoustics. It contains an introduction to Fourier transforms and their properties, sampling and quantization, filters and bandwidth requirements, random signals and noise, and an introduction to four types of processing equipment; the DELTIC, energy detectors, correlation detectors, and beamformers. Course objectives are given in terms of specific questions which a person completing the course should be able to answer. The course is designed to be presented to the personnel involved with the development, operation and employment of acoustic sensors to provide them with a better understanding of the operations accomplished by their equipment and to develop in them a better appreciation of the problems and limitations associated with signal detection in the underwater environment
