A Shallow Water Acoustic Model for an Ocean Stratified in Range and Depth. Volume 1

Abstract

In shallow water the stratification of the medium quite often varies significantly with range as well as with depth, and thus affects the nature of acoustic transmission. Hence, a model of acoustic propagation should be able to accommodate the effect of such changes in the stratification of the ocean. A computer-oriented procedure with its foundations in normal mode theory has been developed for problems of this type. Arbitrary changes in velocity profile, water depth (including a sloping bottom), and bottom composition with range can be accommodated. The effect of mode conversion is included in the analysis. The theoretical procedure is discussed and the mechanics of the resulting computer program are described in volume I.
