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

Abstract

The results of this Phase I STTR show that a number of the currently identified mechanisms responsible for geoclutter are understood and can be modeled. Charles Holland presents a summary of the observed target-like returns from mud volcanoes. The summary of existing diffuse reverberation models shows the approximations made in currently used models. The research by Kevin LePage presents a capability to directly model broadband time series using a coherent summation of narrowband predictions. This capability applied to both diffuse reverberation and recently to discrete clutter is recommended for continued development and transition into a configuration managed simulation product. Applications of this proposed simulation product have been identified within both the AEER and LAMP program in a meeting with representatives of these programs. At the end of the Phase I base program, the goals of a physics based simulation of a broadband time series including the effects of both discrete clutter and diffuse reverberation for frequencies below 5 KHz are attainable. The proposed Phase I option will allow the development of this simulation package to be continued in the time before the Phase II funding is in place.
