    Abstract
  • To accurately describe statistical noise distribution of underwater acoustic signal, we established a statistical noise distribution model of the acoustic signal based on relevant features of symmetric α-stable( SαS) distribution. Firstly, the model configuration for describing noise characteristics of underwater acoustic signal with reverberation was designed by considering the features of noise probability distribution of acoustic signal. Then, the range of index α was determined by trials in tank, lake and sea, respectively, in different acoustic environments. The analysis of the test data shows that the proposed SαS distribution-based model is applicable.
