PGS精密地质声呐是国家“七五”重点科技攻关项目,是跟踪和赶超国际先进水平的研究性课题。挂靠在汉江航道整治项目中,由中国科学院声学研究所东海研究站、交通部水运规设计院等单位共同完成的。该项目的攻关内容是研制一种具备穿透粗砂层的多功能声学测量装置,目的是为港工建设和航道整治中地质勘察提供一种“多快好省”的物探新方法。该系统可以实时地测绘出航船正下方的地层剖面,并具有海底反射系数测量、海底物性估计、双频测深等多种功
PGS Precision Geological sonar is the national “Seventh Five-Year” key scientific and technological projects, is to track and catch up with the international advanced level research topic. Linked to the Hangang Channel regulation project by the Institute of Acoustics, Chinese Academy of Sciences East China Sea Research Station, Ministry of Communications Water Transport Planning Institute and other units jointly completed. The project focuses on the development of a multi-functional acoustic measurement device with penetrating grit layer, which aims to provide a new geophysical method for geotechnical investigation of harbor construction and waterway improvement. The system can plot the stratigraphic section just below the ship in real time and has many functions such as seafloor reflection coefficient measurement, seafloor physical property estimation, dual-frequency sounding and other functions
