Low-Frequency, Long-Range Sound Propagation through a Fluctuating Ocean: Analysis and Theoretical Interpretation of Existing and Future NPAL Experimental Data
نویسندگان
چکیده
Experimental and theoretical studies of low-frequency, long-range sound propagation through a fluctuating ocean are important for many practical problems, e.g. source detection and ranging, communication, and acoustic tomography. The coherence of low-frequency sound waves propagating over megameter distances diminishes noticeably due to sound scattering by internal gravity waves. As a result, the performance of large acoustic arrays degrades.

Studies of the mean field and the coherence function of low-frequency sound waves propagating over long-ranges in a fluctuating ocean are important for many applications, including source detection and ranging. These studies have been done in several papers using different approaches (see [1] for the literature review). For low-frequency, long-range sound propagation, a modal approach for calcu...
متن کاملAPL - North Pacific Acoustic Laboratory
The ultimate limitations to the performance of long-range sonar are due to ocean sound speed perturbations and the characteristics of the ambient acoustic noise field. Scattering and diffraction resulting from internal waves and other ocean processes limit the temporal and spatial coherence of the received signal, while the ambient noise field is in direct competition with the received signal. ...
