AUAMP Resolution Issues. Technical Report

Abstract

This document describes the methodology and results of a sensitivity analysis conducted on the Advanced Underwater Acoustic Modeling Project (AUAMP) transmission loss (TL) calculation. The sensitivity of the TL calculation to range-dependent environmental input parameters and to the model's internal sampling interval was investigated. The model's output transmission loss is analyzed because AUAMP signal excess predictions are ultimately based on calculated TL. In addition, range-dependent environmental data is used directly only in the TL calculation. Reverberation and noise predictions are made using the AUAMP transmission loss calculation as well. The range-dependent environmental data consists of sound velocity profile (SVP), bottom depth, bottom type, and sediment thickness.
