在旋转加速度计重力梯度仪的重力梯度测量原理的基础上 ,本文提出了加速度计标度因子的在线调整方法。此方法对加速度计组合输出信号中的标度因子不平衡信息进行解调 ,通过反馈实现标度因子的调整 。

Based on the gravity gradient measurement principle of rotating accelerometer gravity gradiometer,an online method of accelerometers' scale factor adjusting is proposed in this paper.The method demodulates the summed accelerometer output signals to get the unbalance information of scale factors and realizes adjusting scale factors with the feedback loop.And it can compensate system errors of the gravity gradiometer.
