Description
The book is concerned with the application of modeling techniques and procedures to the investigation of sound propagation in the sea. The modeling method affords a means for studying the laws governing the sound fields in the sea and in other, similar media under controlled laboratory conditions and can be used in underwater acoustics as a coroHary to field experiments. The method has a number of advantages, principal of which are the relative simplicity and low cost of model tests by com parison with fuH-scale tests under oceanic conditions, the high accuracy of acoustical mea surements, excellent reproducibility of the measurement results, and the capability of rapidly varying the experimental conditions, which, unlike the conditions of field experiments, are under complete control. For the modeling of sound propagation in the sea the latter is treated, depending on the problem to be solved, either as a volume-homogeneous medium or as a medium possessing regular and randomly-distributed inhomogeneities. We direct our primary attention in the book to the modeling of layered-inhomogeneous media, but we also discuss separate problems bearing on the study of sound propagation in the sea. It is demonstrated in examples how modeling is employed to investigate the sound field in the ocean for certain typical vertical distributions of the velocity of sound in the ocean.
