Summary
Chapter 3 investigates the applicable conditions of the Born and Eikonal approximations for scalar wave scattering in random velocity fluctuations characterized by the power spectral density function. The Born approximation leads to the anisotropic scattering coefficient, which represents the directional scattering power per unit volume. The Eikonal approximation leads not only to the angular spectral function that governs narrow-angle ray bending but also to travel–distance fluctuation.
