Scattering of Underwater Acoustic Signals from a Rough Moving Surface.

Abstract

The research dealt with surface scattering and consisted of an experimental as well as a theoretical component. The experimental work was conducted in a model tank equipped with a wind tunnel to produce a wind-driven surface. The tank is very well instrumented and interfaced to a computer so that the experimental results can be accepted with considerable confidence. Four separate projects are included in the work covered by this report. These are: (1) Calculation and Measurement of first and second-order moments of the channel transfer function; (2) Spatial correlation between two receivers; (3) Power scattered in directions other than forward; and (4) Asymmetric Doppler amplitudes in forward scatter. Each one of these projects is briefly discussed and summarized.
