Ostashev, V. (1997). Acoustics in Moving Inhomogeneous Media. London: CRC Press, https://doi.org/10.4324/9781482271843

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. The book is an invaluable resource for engineers and scientists who work on outdoor noise control, on acoustical detection and ranging i
