Abstract
The merchant ships including passenger ship target are one of important source of sea environment noise, and is also the primary background jam of underwater passive detection and target recognition, especially areas in shore. Consequently, this paper mainly focuses on measuring and analyzing acoustic spectrum and signature of underwater radiated noise originated from a passenger ship with more than ten thousands of tonnages, especially focusing on the distribution of power and frequency, the amount of stable line-spectrum, structure of envelope modulation spectrum and its stability of amplitude. And the analysis results can be further applied in the studies on underwater passive detection, target recognition and ship acoustic design, especially for passenger ships.
