Analysis of Internal-Wave Measurements Using a Vertical Acoustic Array

Abstract

This contract will plan and carry out an ocean acoustic experimental program. Expected internal wave induced fluctuations were calculated for numerous possible experimental configurations involving a source and receiver placed near the Bahamas in the Atlantic Ocean. Ranges up to 400 km were treated. The source and receiver depths were varied from the sound-channel axis (at about 1300 meters) up to the surface. Fluctuations in arrival time and arrival angle were particularly investigated for all the geometrical optics rays for each configuration. Simulation of singal processing schemes were extensively carried out to be sure that internal wave fluctuations would not degrade signal to noise to any significant degree.
