Abstract

This paper reports an attempt to measure the asymmetry of wind-generated water waves by using acoustical methods. A 40-foot wind-tunnel water flume provided a controlled water surface that was insonified from above at 162 kHz with pulses 30 µsec in duration (5 cycles). The scattered-pressure amplitude pulses were analyzed statistically as a function of the shear stress produced at the water surface by the wind....
