摘要
分析了在甚宽频带地震计的时域标定中存在的各种噪声 ,探讨了相应的处理方法 ,重点阐述了对阶跃标定影响最大的长周期漂移噪声的处理方法———漂移曲线拟合法。
There are various noises in time domain calibration of Very Broadband Seismometer. In this paper, several methods for noise data processing are discussed. Especially, the Shift-Curve-Fitting method is developed to treat long-period drift noise that very much influences the time-domain calibration.
