Abstract
The ONR-funded Target and Reverberation Experiment 2013 (TREX13) took place in the Northeastern Gulf of Mexico near Panama City, Florida, during April and May of 2013. During this trial, which took place in a shallow water (20 m deep) environment, several sets of one-way and two-way acoustic transmission loss and reverberation data were acquired. Closed form expressions are derived to trace the uncertainty in the inputs to a Gaussian beam propagation model through the model to obtain an estimate of the uncertainty in the output, both for transmission loss and for reverberation. The measured variability of the TREX environment is used to compute an estimate of the expected transmission loss and reverberation variability. These estimates are then compared to the measured acoustic data from the trial.
