Abstract
Laboratory analysis and random sample processing of field records of surface ships noise collected in the waters of the White, Barents, and Norwegian Seas were used in the study of ultra-slow signal fluctuations’ influence on the passive listening noise stability. Experiments show that signal fluctuations enable a potentially high noise stability when a short accumulation time interval (a few seconds) and a long accumulation time interval (one hundred and more seconds) are used simultaneously. A long accumulation time reduces the likelihood of contact loss during a decrease in the signal level. A short accumulation time can provide significant gain in the detection range during periods when the fluctuation process leads to a short-term increase in the signal level.
