摘要
The authors design the maximum normalization algorithm which can effectively eliminate seismic signals,distorted signals and other interfering signals from the ambient-noise recorded in a frequent earthquake region such as Yunnan.First,we apply this algorithm to pre-processing the recorded ambient noise,and then adopt the multi-taper deconvolution method for the processed data to extract Green’s function with high signal-to-noise ratio and relative amplitude information.
