Fluctuations of Mid-to-High Frequency Acoustic Waves in Shallow Water
نویسنده
چکیده
Scientific objective of this research is to understand acoustic wave propagation in a dynamic environment in two different frequency bands: (a) Low frequency band (50 Hz to 500 Hz). The subject of interest in this band is to assess the effect of environment anisotropy on acoustic wave propagation, with an emphasis on the separation of different effects due to horizontal refraction and mode coupling from adiabatic regimes, (b) Mid-to-high frequency band (500 Hz to 25 kHz). The subject of interest in this band is to assess the effects of the water column and the sea surface variability on acoustic wave propagation for underwater acoustic communications and tomography applications.

متن کاملFrequency dependence and intensity fluctuations due to shallow water internal waves.
A theory and experimental results for sound propagation through an anisotropic shallow water environment are presented to examine the frequency dependence of the scintillation index in the presence of internal waves. The theory of horizontal rays and vertical modes is used to establish the azimutal and frequency behavior of the sound intensity fluctuations, specifically for shallow water broadb...
