Chapter 2. Methods of calculation of Nonlinear interactions in sound beams Small parameters used in the calculation of wave interactions Solution of the equations of hydrodynamics by the method of successive approximations Calculation of the secondary field by the Green's function method: The Westervelt formula Estimates of the basic characteristics of parametric radiators by means of nomograms...

Inverse Problems in Underwater Acoustics

The paper presents an overview of the inverse problems associated with applications of underwater acoustics. The problems are classified into four main categories, according to the recoverable quantities : Acoustic source localization, bottom identification, ocean acoustic tomography and target recognition. The paper gives emphasis to the three first categories, and includes methods to solve th...
