This is the first book to offer a complete and rigorous study of sound propagation and scattering in moving media that have regular and random inhomogeneities in adiabatic sound speed, density and medium velocity. Although the emphasis is on mathematical development, the author has provided many numerical examples of practical interest taken from relevant contexts in atmospheric and oceanic acoustics. These include the effects of ocean currents and the extent to which the vector wind effects in the atmosphere may be treated in terms of effective sound speed gradients. The book is an invaluable resource for engineers and scientists who work on outdoor noise control, on acoustical detection and ranging in the atmosphere, and on acoustal remote sensing of the atmosphere and ocean, whether they are based in the industry, or government and military laboratories and institutions.
