Abstract
Several high frequency experiments in recent years have been directed towards assessing signal variability as a function of channel environmental parameters. In this paper, results from one of these experiments in a shallow water region are shown. Acoustic communication coded signals were transmitted between a source and two receiver arrays separated 1 and 2 km respectively while detailed measurement of the channel environmental parameters were recorded. Channel impulse response function and the correlation time of the channel are obtained. Ray theory is used to analyze and interpret the experimental data. Arrival time-angle fluctuations were found to be directly correlated with the environmental variability due to ocean dynamics in the experiment region.
