基于被动声学技术的海洋生物测量研究进展
Research progress of marine organisms based on passive acoustics technology
摘要
Abstract
This paper summarizes the importance of survey of marine organisms based on passive acoustics technology, introduces the research background, current situation, issues and tendency of marine fish survey based on the the technology, lists the common passive acoustics measurement equipments and digital signal processing methods, including data acquisition, preprocessing, endpoint detection, feature extraction and recognition technology, and analyses the potential application of above measurement technology on study of marine fish habitats, living habits and influence of human activities on the fish population. However, a lack of familiarity with the biology and passive acoustics knowledge has hampered the development of this technology. Through listing the sonic studies of Cynoscion nebulosus and Gadus morhua. the top priorities of passive acoustics technology study in the future are put forward, such as establishing the various passive fish feature library, analyzing the passive acoustic radiation mechanism of fish, dolphins and other marine organisms, studying on the typical acoustic feature parameters and relationship between fish sound and the special behaviors.关键词
