Predictability Limitations of Long-Range Sound Propagation

Abstract

To determine the predictability limitations of acoustic signals in long-range propagation. The effects of short-wavelength mesoscale structure are examined from the ray and wave chaos points of view at megameter ranges, and is shallow water the effects of bathymetric variability are examined from the ray and wave points of view at ranges of many tens of kilometers. Finite frequency effects and measurement techniques for the experimental observation of wave chaos in the ocean are emphasized.
