Abstract:

According to the frequency domain characteristics of ship’s radiated noise，and considering from three aspects，which are the ship radiated noise line spectrum，the development trend of the spectral density and signal energy of peculiar frequency band，the consistency analysis of the simulation data and the measured data of the ship’s radiated noise is carried out to evaluate the confidence of the simulation model of the ship radiated noise comprehensively. Through analyzing confidence of ship radiated noise simulation model，this paper provides theoretical support for the confidence of simulation signal source of ship’s radiated noise.
