摘　　要：文章介绍了海底声学探测与底质识别技术的现状及最新进展。重点介绍线性调频声呐 (CHIRP)技术和非线性调频声呐技术 (参量阵声呐 )在海底沉积层结构、海底地形地貌探测及其在海底沉积物的底质属性分类识别方面的应用。并简要介绍国内外在线性和非线性调频声呐技术及用于沉积物属性识别方面的最新专利技术或最新进展。Some new progress in detecting the geological formations and sediment properties by acoustic signal are presented in this paper.The linear or non linear modulate frequency sonar and its applications in detecting the geological formations and classifying seafloor sediment properties are introduced.The new patents and three kinds of non linear sonar used in classifying seabed sediment by its acoustic parameters are also show in the article.
