摘要

针对地震信号随机干扰和规则干扰的特点，运用二维小波变换的理论，设计了相应的变换域去噪滤波器．理论记录和实际野外记录试算表明，二维小波变换具有较强的信噪分离作用．只要运用得当就能取得满意的效果．
A filter is designed to kill noise in accordance with the characteristics of the seismic signals having a random disturbance and regular disturbance and with the theory of the two dimensional wavelet transformation.Trial computations of a theoretical record and an actual field record showed that the two dimensional wavelet transformation has Abvious effect on separation of signal from noise.As long as it is used properly,satisfactory result can be obtained.
