COMPUTATION OF ACOUSTIC WAVE PROPAGATION IN A RANGE DEPENDENT STRATIFIED SEA MEDIUM

摘要

Acoustic Wave Propagation inside a laterally inhomogeneous layered sea medium is examined using analytical techniques. Starting from the computation of response function of the stratified medium, integral equation techniques are employed to analyze the case of inhomogeneous sea medium. The use of contour integration techniques allows the development of field expressions in terms of normal modes of the stratified medium with arbitrary number of layers. Field calculation is carried out for a sinusoidal lateral inhomogeneous environment. Numerical computations are carried out and the effects of inhomogeneites are examined.
