摘要：

In this paper, a new correlation processing method-vertical correlation method is presented. A mathematics principle of vertical correlation method is studied and examples of simulation and application are given. The results show that vertical correlation method has strong noise-reduction ability, eliminates strong-noise's influences to calibration precision and raises greatly frequency-domain calibration precision for very broadband seismometer.
