联合多波束和侧扫声呐的浅海磁异常探测技术
Shallow sea magnetic anomaly detection technology combined with multi-beam and side-scan sonar
摘要
Abstract
In response to the technical requirements for fine seabed environment detection in offshore development and con-struction,this paper innovatively constructed a collaborative detection system integrating multi-beam sounding,side-scan sonar,and marine magnetic surveying.The system utilized the multi-beam system to achieve a centimeter-level bathymetric model,relied on high-resolution side-scan sonar imaging to analyze seabed surface structures and potential targets,and com-bined an optical pump magnetometer to capture magnetic anomaly signals.Based on multi-physics simulation technology,a magnetic feature database for typical seabed targets was established,and magnetic anomaly targets were identified and located using professional analysis software.The practical application in a certain marine area in Guangdong Province shows that this technical system successfully identified multiple targets with significant magnetic anomaly characteristics.The research effectively integrates the advantages of various geophysical detection methods,significantly enhancing the compre-hensive detection and identification capabilities for subsea artificial structures,sunken ships,pipelines,and other targets.It provides important technical support for offshore engineering surveys,marine resource development,underwater archaeol-ogy,and national defense security.关键词
