摘　　要：舰船噪声建模是研究水声信号处理和声纳系统的关键技术。从舰船噪声的时频域特性出发建立适应性广的舰船目标噪声模型,提出基于特征相似的模型可信性评估方法,并对舰船噪声模型进行可信性分析。Ship＇ s radiation noise modeling is the key technique for the research of underwater noise processing and sonar systems. In this paper, the model was established based on the time-frequency characteristic of the ship＇ s radiation noise. A method of model creditability assessment based on characteristic similarity was proposed and used to analyze the creditability of the ship＇ s radiation noise model.
