摘要
研究窄带高频声信号海底底质分类方法。应用相平面轨迹统计方法对5个实验站点的高频(50 kHz)海底回波数据进行分析,提出了1种新的特征量提取方法,初步可对3类海底分类。结果与海洋图集结果吻合较好。
A seabed sediment classification method using high frequency narrow-band echo sounding signals is studied.A phase plane tracking statistical method is used to analyze the high frequency(50 kHz) echo sounding signals at five spots.A new identification quantity,which is useful to seabed classification,is proposed and the primary results show that three types of seabed can be identified and they are in good agreement with published data.
