Effects of Convergence Zone Multipath on Crosscorrelation.

Abstract

This document contains the slide presentation entitled 'Effects of Convergence Zone Multipath' given at the 110th meeting of the Acoustical Society of America 4-8 November 1985, in Nashville, Tennessee. Recent work by Hauck indicates autocorrelation processing may be adversely affected by the large number of acoustic rays from a source within a convergence zone. The object of the current study is to examine the effect of CZ multipath on cross-correlation of frequency hopped pulses. The sensitivity of the correlation to source or receiver depth and the location of the source within a convergence zone is examined using the Generic Sonar Model. Keywords include: Acoustic Multipath, Convergence Zones, and Crosscorrelation.
