背景噪声成像方法采用的是自然稳定的噪声源,具有可重复和时间上稳定等特点,回避了传统成像方法的地震分布不均和定位不准等缺点,因而成为当前地球物理研究的热点.从格林函数提取、噪声源特性和成像工作中取得的成果几个方面对背景噪声成像方法进行综述.

Ambient noise tomography based on natural noise is repeatable and stable, it overcomes several important limitation of traditional methods based on earthquakes, ie. uneven distribution of earthquake sources and uncertainty in earthquake location. Now it is a new promising technique. In the present show the extracting Greens function, origin of ambient noise and tomography.
