Modeling of Echoes from Extended Targets in Shallow Water

Abstract

This document describes an effort to integrate existing target and environmental models to allow the prediction of echoes from targets in a shallow water environment using realistic transmitted waveforms. A primary objective was the development of a numerical tool that could examine the effect of a medium on target echo characteristics. Echoes were generated and comparisons made in a shallow water environment by using a linear frequency modulated signal, the generic sonar model, and the frequency response functions of a rigid sphere and an array of five spheres.
