摘要

The long-term goal is to contribute to the understanding of long- range propagation of acoustic pulses in deep ocean environments. Emphasis is placed on broadband pulses centered at around 100 Hertz in oceans that have a well defined acoustic waveguide. This effort directly compliments the Long- range Ocean Acoustic Propagation Experiment (LOAPEX) that was performed in the fall of 2004. A primary objective is to test the hypothesis that an stochastic environmental model that includes internal waves and spice is adequate to explain the multiple forward scattering of acoustic pulses as they are propagated in range. The stochastic model is based on measurements of temperature, salinity, and pressure taken during LOAPEX. Of primary consideration is to compare model results to LOAPEX data which used source of approximately 75 Hz, but extrapolation to other source frequencies (e.g. 250 Hz) is also an objective.
