【摘要】：海洋環(huán)境復(fù)雜多變,并且水聲信號信道非常特殊。本文利用高階譜能夠抑制高斯噪聲的特性,將其應(yīng)用于船舶多噪聲的識別,并采集兩類船舶信號進(jìn)行實(shí)驗(yàn)。實(shí)驗(yàn)結(jié)果表明,本文所采用的高階譜能夠有效的識別和分離出船舶噪聲。
[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.
