| 摘 要： | 在理想情况下,海洋重力仪的测量数据经厄特弗斯校正和交叉耦合改正后应不受载体运动状态的影响,即与仪器的运动状态没有任何的相关性。但实际测量结果表明,当海况较差时,载体的运动状态对S型海洋重力仪的测量数据有着较为明显的影响。通过对实测重力数据和仪器运动状态的相关分析,指出仪器原来交叉耦合改正的不足,并且利用线性回归进一步对重力数据进行了改正。

| Abstract: | Corrected with cross coupling,the measureddata of S model Gravimeter should not be under the influence of the ship's moving state if the meter is performing perfectly.Butthe actual result shows that the effect is more obvious when the sea is in a worse condition.Through the correlation analysis between the actual data and ship's state,the insufficiency of meter's cross coupling correction is pointed out in this paper.Furthermore,the gravity data is re-corrected by means of linear regression. |
