【摘要】：海洋環(huán)境復(fù)雜多變,并且水聲信號(hào)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(shí)別,并采集兩類船舶信號(hào)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(shí)別和分離出船舶噪聲。
[Abstract]:The marine environment is complex and changeable, and the channel of underwater acoustic signal is very special. In this paper, the high order spectrum is used to suppress the Gao Si noise, which is applied to the recognition of ship multi-noise, and two kinds of ship signals are collected for experiment. The experimental results show that the high order spectrum used in this paper can effectively identify and separate ship noise.
