One of the most important problems, encountered in the analysis and design of underwater information transmission systems using ultrasonic waves, is how to quantitatively evaluate the effect of multi-path propagation due to surface reflection The author was provided with a probabaistic model to deal with the multi-path propagation problem. For the purpose of demonstrating the applicability of the model, the experiments were carried out in an unechoic water tank with a free surface. The results and the statistical analysis obtained by using a digital computer are described It has become evident that the multi-path propagation plays an important role in the trade-off among various design parameters. Therefore the concepts developed are to be applied to the design of an underwater telemetry system.
