| 摘 要： | 基于相空间重构方法,从海底回波信号的相平面和相空间中提取了三个特征量:一阶距、相似序列重复度和熵,应用于海底底质分类。通过对海上实验数据的分析表明:这三个特征参数能有效地将两类海底分开,结果与海底采样分析吻合良好。

| Abstract: | Based on phase space reconstruction,three characteristic parameters,first order moment,sim-ilar sequence repeatability and entropy,are extracted from seabed echo signals.Statistical properties of the three parameters are used in the seabed classification.Results of sea experiments show that these param-eters can be used to classify two seabed types,with good agreement with sediment sampling results. |
