重力梯度张量分量转换处理误差研究

摘要

Based on the gravity gradient transformation model experiments for different data length,the frequency singular points in the transformation expressions was found to be the error source by spectrum and anomaly distortion analysis.The transformation error will de-crease and the result will be better as the frequency resolution improvement with the data length increasing.%从Uxy分量不同数据长度重力梯度张量分量转换处理模型实验入手,通过频谱畸变和空间域转换误差对比分析,发现转换处理公式中频率域奇点是转换误差产生的根源,增加数据长度、提高频率分辨率可减小转换处理误差、改善转换处理效果.
