Abstract

Recent work by Hauck [NUSC TD 7409] 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 [H. Weinberg, NUSC TD 5971C]. Results for both first and second CZs will be presented.
