    • Abstract
  • 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 vetical correlation method has strong noise-reduction ablity, eliminates strong-noise’s influences to calibration precision and raises greatly frequency-domain calibration precision for very broadband seismometer.
