【摘要】 通过对舰船辐射噪声频谱特性的深入分析,给出了一种目标特征提取的方法。并在建立目标通过特性数学模型的基础上,结合所提取的特征量,分别对两类目标在不同横距、不同深度、不同信噪比下,噪声信号全频段和各频段的通过特性进行仿真。更多还原

【Abstract】 This paper analyzes the frequency signature of real-detected ship noise, proposes a kind of method to extract the object signature, builds up object抯 through signature mathematical model and respectively simulates the through signature of whole frequency channel noise and each frequency channel noise for two class of objects on different conditions. The research result can apply to the ship noise identification.更多还原
