COHERENCE OF ACOUSTIC SIGNALS IN THE OCEAN
Abstract
Hydrophone installation and experimental procedures are described for determining the coherence of pseudo-random signals transmitted through the ocean in the Bermuda area. Curves of the correlation anomaly between the expected percent correlation and the measured correlation are shown for various hydrophone spacings and ranges. It is concluded that there is no measurable change in coherence due to dstortion of the signal by the medium in the present data. (Author)
