摘要

Seemingly ocean is silent but this is not so true. Ocean is always filled with a circumstantially interfering noise known as ambient noise produced by turbulence, heat, wind and some natural phenomenon and other activities. This ambient noise put considerable intrusions in underwater acoustic communication which is so crucial for Oceanographic Monitoring. There exist numerous undersea applications under the umbrella of Oceanographic Monitoring like climate change detection, offshore explorations, oceanographic data acquisition, pollution monitoring, disaster prevention, seismic monitoring etc. In recent years, on different widespread geographical sea regions, this ambient noise has been observed for showing the varying shapes of Gaussian distribution. In order to design and deploy any undersea application, it is of prime importance to explore the variations in the shape of statistical distribution of background underwater ambient noise. This paper has been intended to put forward a computational design approach to compare and find the proximity of experimental/empirical noise pattern with that of hypothesized Gaussian noise pattern using Kolmogorov-Smirnov (KS) test statistic. This computation for the noise pattern recognition is so much conducive to simulate the oceanic environment using the hypothesized / controlling parameters of Gaussian noise pattern in order to design and deploy any undersea application.
