摘要

本文研究了数字地震记录仪记录的存在地震噪声的地震信号的改进地震参数估计问题。本文分两个阶段研究了一种新的算法。首先对地震信号的功率谱进行估计，然后通过谱减法或维纳滤波将估计的噪声从观测信号中去除。该算法在保留地震信号信息的同时，经过增强处理，给出准确的地震参数。

Seismic signal enhancement through statistical (Wiener) approach

This paper addresses the problem of improved earthquake parameter estimation of seismic signal in the presence of seismic noise recorded by Digital Seismic Recorder. A novel algorithm is investigated in two stages. First, the noisy earthquake signal power spectrum is estimated and the second step is to eliminate the estimated noise from the observed signal by spectral subtraction or Wiener filtering. This algorithm preserves the earthquake signal information and gives accurate earthquake parameters after enhancement process.
