Advanced Physics-Based Modeling of Discrete Clutter and Diffuse Reverberation in the Littoral Environment

Abstract

In response to the Navy STTR Topic N03-T011 "Physics-based modeling of Acoustic Reverberation in the Littoral Environment," a team representing PSI ARL-PSU and NRL-DC was assembled to develop a broadband time series simulation capability for both discrete clutter and diffuse reverberation. This simulation capability is based upon the work by Kevin LePage (NRL-DC). who participated on this STTR as an outside funded resource. and uses the coherent summation of narrow band results using normal mode methods to generate the broadband time series simulations. This high level of simulation fidelity was proposed for use in the AEER (Advanced Extended Echo Ranging) programs as a tool for active. coherent sonar system development. Due to funding limitations in FY 07 at NAVAIR. that transition was not possible even with a high level of interest from the AEER program manager. The product of this Phase II STTR does not replace an existing modeling capability within the proposed program but rather will provide an entirely new simulation capability.
