The spatial processing of acoustic signals measured in field experiments and the creation of special acoustic signals to be radiated for specific purposes on the sea shelf are just two examples out of many of signal processing for shallow water acoustics. In doing such processing, it is important first of all to determine the commonly used characteristics of the acoustic signal such as its amplitude, phase, spectral density, etc. Shallow water signal processing often deals with random signals, as the signal from a remote sound source passes through a randomly inhomogeneous medium in field experiments and is detected against an acoustic noise background, not to mention the case when the acoustic noise itself is the object of study. Techniques for measuring these signal characteristics, including techniques for estimating measurement accuracy as a whole, are well known and similar to measurement techniques in other fields of experimental physics. Techniques are described in many monographs [see, e.g., Bendat and Piersol (1986); Max (1981)], to which we refer our readers. In this book, we will briefly consider some basic relations commonly used when processing such acoustic data.
