摘要
本文讨论利用声学遥测方法进行海底沉积物分类的目的、用途及该项技术的发展背景和现状。重点介绍目前主要的用于浅、表层沉积物分类的声学遥测方法，包括选通等幅脉冲、宽频带脉冲、连续线性扫频脉冲等正入射方法和侧扫声呐、多波束测深等斜入射方法。回顾它们的发展历史，评述它们的技术现状。
At first,remote acoustic classification of seafloor sediments was discussed for its purpose,application and technological background.Then,main remote acoustic classification methods were presented in a systematic way. These methods included normal incidence classification studies with gated CW pulses,wideband width pulses and chirp pulse,and off-normal incidence classification studies such as side-scan sonar and multibeam echo sounding.Their developing histories and present condition were studied,and their further development was discussed.
