Channel Characterization Modeling

Abstract

Before underwater transducers and hydrophone arrays are deployed for use it is necessary that researchers have an idea of how successful a particular sound waveform would be in transmitting information to the receivers. Currently rough calculations are used to predict how a specific waveform would be altered by its environment during its travels through the water. There is a need for a program or programs that would take a specific environment's parameters, as modelled by programs like the US NUWC's GSM, and more accurately indicate the suitability of a waveform's parameters as well as other transmission and receiver parameters. This will be an aid to determining optimal combinations of these parameters. Sea trials can then be set up using these sets of preferred parameter combinations with the expectation of obtaining high quality results.
