Multipath Interference Prediction Study for Dabob Bay and Nanoose Bay Sonar Channels

Abstract

The purpose of this study is to determine the feasibility to communicate tracking data by UQC underwater telephone to submarines operating within the 3-D tracking areas in Dabob Bay and Nanoose Bay. The ability to communicate reliably and at a sufficient data rate depends upon three factors. The first factor is the ability to reliably transmit sound from a source to a receiver. Assuming that the power level of the transmitter is sufficient to produce an acceptable signal to noise ratio at the receiver, the ability to transmit sound from one point to another depends mainly upon the prevailing velocity profile and geometrical characteristics of the sonar channel. The second factor is the arrival time difference between a direct ray and other rays traveling paths different from the path of the direct ray.
