Investigation of the Applicability of AUAMP in Shallow Water Technical Report

摘要

The Office of Naval Research Detachment, Stennis Space Center tasked TRW toinvestigate the applicability of the Advanced Underwater Acoustic Modeling Project (AUAMP version 2.6) in shallow water and transitional (slope) ocean environments. AUAMP was developed for deep water applications and analysis was required to determine its appropriates in shallow water environments. This document presents preliminary results of this analysis. In addition, this report attempts to separte the environmental input dependency from the model algorithm accuracy when using AUAMP to make acoustic and system predictions. This document is an intermediate report in the process of the validation and investigation of AUAMP version 2.6 in shallow water and slope environments. This task investigates the applicability and sufficiency of the AUAMP model algorithms, data bases, and modeling assumptions in shallow water. Initially, this evaluation addresses the sensitivity of model algorithms to environmental input parameters as well as their appropriateness for use in shallow water environments.
