Beschreibung:
This book offers a uniquely complete and rigorous study of sound propagation and scattering in moving media that have deterministic and random inhomogeneities in adiabatic sound speed, density, and medium velocity. It is a resource for engineers and scientists who work in atmospheric and oceanic acoustics, aeroacoustics, outdoor noise control, acoustical detection and ranging in the atmosphere, and acoustic remote sensing of the atmosphere and ocean. It will also be required reading for researchers who use numerical methods in these fields.
