Various types of phase measurements have been introduced into ocean acoustic measurements since the early 1960s, many utilizing the increased precision possible with digital processing. These are usually considered natural and basic by their developers, but are frequently misunderstood and mistrusted by those they were designed to benefit. This paper explains a recent phase technique which was used in the Heard Island Feasibility Test data analysis of the Ascension Island receptions. It revealed that the common phase fluctuations of the wideband M‐sequence receptions were not random, but were caused by minor deviations of the source ship track 9200 km away. |
