摘　　要：地震波干涉法的提出与应用丰富了对地震波传播规律的认识和研究,被认为是地球物理发展的一大进展.其基本原理是对不同位置接收到的地震波信号进行相关而得到新的地震信号,该信号能反映原始地震波信号所不能反映的信息.本文详细介绍了地震波干涉法的原理及其在地球物理学特别是地震勘探领域中的应用.首先,重点介绍了地震波干涉法理论的提出、发展和完善的过程;其次,讨论了目前应用的地震波干涉法的不同的数学实现方式;最后,介绍了用地震波干涉法的数值实现过程以及用地震波干涉法进行成像的研究进展.The development and application of seismic interferometry, which is assumed as one significant advancement in geophysical community, have enriched the knowledge and study of seismic wave propagation. The basic idea of seismic interferometry is that if we cross-correlate the different seismic signals at different locations, we could retrieve a new signal, which could reflect the information that could not be seen from the original seismic waves. In this paper, we briefly review the principles of seismic interferometry and the application in geophysical fields, especially in exploration geophysics. We first focus on the birth, historical development and enrichment of seismic interferometry, then discuss different mathematical ways to do seismic interferometry, and finally introduc the process of interferometry from a numerical point of view and introduc the advancement interferometric imaging.
