摘　　要：对舰船噪声模型进行可信度评估,是合理运用噪声模型进行仿真分析的重要环节。通过分析时频特征,建立了舰船噪声模型;提出了一种基于特征相似的舰船噪声模型可信度评估方法:先在时域、频域分别对模型输出噪声与实际噪声的各特征相似度进行分析,再用层次分析法对整个噪声模型进行可信度评估,并对实测数据进行应用与分析。分析结果表明:该舰船噪声模型具有较高的可信度。Credibility evaluation plays an important role in designing the ship radiated-noise simulating models.A ship radiated-noise model was firstly set up based on the analysis of the characters in the domains of both time and frequency.Then a method based on characteristic similarity was proposed to estimate the credibility of the model.After checking the similarity of several characters of the real and imitated noise,AHP was used to make the credibility evaluation of the model as a whole.The result obtained from the application and analysis of the data proves that the model of the ship noise is of high credibility.
