【摘要】 将常规地震勘探视作噪声的信号作为有用信息,从一对地震台站之间地震背景噪声的互相关函数得到这一对台站间的格林函数,利用得到的格林函数对地下结构成像,这是当前跨地震学研究的热点之一.回顾了背景噪声成像的发展历史,阐述了目前的方法特点,展望了将来的发展趋势.更多还原

【Abstract】 At present,the hot topics in cross seismology follow as:treating the signal which is seemed as the noise in conventional seismic exploration as useful information;obtaining Green’s Function between a pair of seismic stations from the cross-correlation function of the ambient seismic noise between them;imaging for underground structure using the obtained Green’s Function.In this paper, the historical development of ambient seismic noise imaging is reviewed,current methods and characteristics are described,and development trend of the future is prospected.更多还原
