【摘要】:海洋环境复杂多变,并且水声信号信道非常特殊。本文利用高阶谱能够抑制高斯噪声的特性,将其应用于船舶多噪声的识别,并采集两类船舶信号进行实验。实验结果表明,本文所采用的高阶谱能够有效的识别和分离出船舶噪声。
[Abstract]:The ocean environment is complex and changeable, and the underwater acoustic signal channel is very special. This paper uses the high order spectrum to suppress the characteristics of Gauss noise, and applies it to the recognition of the ship's multi noise, and collect two kinds of ship signals to carry on the experiment. The experimental results show that the high order spectral energy used in this paper can effectively identify and separate the ship noise.
