摘要:: 利用地震台记录的背景噪声数据,进行台站对之间数据互相关以获得反映地下介质信息的格林函数,是目前地震学领域理论研究和实际应用方面的前沿和热点。首先介绍了噪声互相关应用的发展历史,之后对其在面波成像、体波信号提取与体波成像、监测地下介质波速变化与衰减、地震定位、噪声源分析与时移校正等多个方面的应用进行了阐述,最后针对目前背景噪声互相关应用的发展进行了分析与讨论。

Abstract:: Obtaining Green's function,which can reflect the information about the underground media by cross correlating the ambient noise data recorded by seismic stations,is the frontier and hot spot of theoretical research and practical application in the field of seismology.This paper firstly introduces the evolution of the noise cross-correlation application,and then expounds its application to surface-wave tomography,body-wave signal extraction and body-wave imaging,monitoring of variation and attenuation of the wave-velocity of underground media,earthquake location,analysis of noise source,and time-shifting correction.Finally,the prospect of the application of ambient noise cross-correlation is discussed.
