sea-bed reverberation

To deal with the problem of seabed reverberation of side-scan sonar images in target detection, we propose to estimate the targetin images by the magnitude of higher-order spectrum----bispectrum.
在海底目標(biāo)檢測(cè)中，針對(duì)側(cè)掃聲納圖像受海底混響干擾嚴(yán)重的缺點(diǎn)，提出了將高階譜中雙譜的譜峰值大小作為圖像中目標(biāo)是否存在判斷方法。
