一种地震波信号检测与处理方法

Method on Detecting and Processing Earthquake Wave Signal

在分析了微弱信号一般提取方法的基础上,介绍利用人工激震源产生的地震信号在勘测地质结构工程中的处理方法,由于采集的信号很微弱、信噪比很低,可利用信号存储及叠加技术,采用逐次增强信号并提高信号的信噪比的方法,从而提取包含地质结构信息的信号。

In geological surveying engineering, because of weak earthquake wave signal and low SN ratio, the signal can not be distinguished. By storing and accumulative technique, the SN ratio can be increased and a good signal also can be obtained.
