G-882G型海洋磁力仪在海洋工程勘察中的性能分析与应用

Performance analysis and application of G-882G marine magnetometer in marine engineering investigation

海洋磁力仪测评是海洋磁力测量前期技术准备内容,也是现阶段海洋磁力测量规范要求的重点环节。针对现阶段海洋磁力仪产品型号众多、技术复杂、应用广泛的特点,文章选择G-882G型海洋磁力仪展开研究。G-882G型海洋磁力仪是光泵海洋磁力仪,从上个世纪六十年代发展起来,是一种借助光泵技术制成的一种高灵敏度磁力仪。结合海洋磁力仪性能指标内涵,提出符合实际的海洋磁力仪性能指标测试分析操作方法,以G-882G型海洋磁力仪为例对海洋磁力仪的主要指标进行分析,旨在为海洋磁力仪性能测试工作提供更多参考。

Evaluation of marine magnetometer is the preparatory content of the early technical preparation of the o- cean magnetic force measurement, and it is also the key link of the requirements of the current phase of the marine magnetic force measurement. In view of the characteristics of the marine magnetometer with numerous products, com- plex technology and wide application, the G-882G type marine magnetometer is selected for the study. The G-882G type marine magnetometer is an optically pumped marine magnetometer. It developed from the 60s of last century. It is a highly sensitive magnetometer made by optical pumping technology. According to the connotation of marine magne- tometer performance index, proposes several methods for performance test of marine magnetometer practical analysis, with G-882G as the main index of marine magnetometer of marine magnetometer is analyzed, aiming to provide more reference to the work of marine magnetometer performance test.
