曲波变换在微地震信号中的去噪

Denoising of curvelet transform in micro-seismic signals

本文通过对Curvelet变换的研究,利用Wrapping算法对微震数据进行处理,分割成不同的尺度不同方向的区域,然后对不同尺度不同方向的元素进行预测滤波,在预测滤波的基础上进行带通滤波处理,使得结果更加清晰、明显。

The seismic data are segmented into different scales with different directions and sizes in this paper by Wrapping algorithm base on the Curvel t tra sform.Band-pass filter is c r ed out on the basis of the pr diction filtering of the micro-seismic signal elements in dif er nt direction ,whh make thslsmr apparent.
