Design Study of Remote Sensing for Ocean Surface and Interior Activity.

Abstract

This is a study to determine the feasibility of using acoustic instruments to observe upper ocean processes. The processes include surface gravity waves, upper ocean turbulence, Langmuir cells and near currents, and internal waves. The acoustic surface backscatter and the acoustic volume backscatter from bubbles and suspended matter will allow the processes to be observed and tracked. The main issues are spatial resolution, volume coverage, sampling rate, and velocity measurement or tracking accuracy. The acoustic properties of the scatterers were modeled to determine signal detectability, hence volume coverage and resolution. Existing velocity measurement techniques and a new tracking method were also modeled. From all the submodels, a system performance prediction model was constructed, from which recommendations were made regarding sonar configuration, operating frequencies, and other system specifications. Keywords: Remote sensing.
