【摘要】 在勘测地质结构工程中,利用人工激振源产生的地震信号了解地质结构,由于采集的信号很微弱、信噪比很低,本文介绍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。更多还原

【Abstract】 In geological surveying engineering ,because of weak vibration wave signal and it,s low SN ratio,the signal can not be distinguished. By storing and accumulative technique ,the SN ratio can be increased and a good signal which includes information of geo-structure can also be obtained.更多还原
