Method of suppressing vibration seismic signal correlation noise

机译:抑制振动地震信号相关噪声的方法

摘要

A method of seismic prospecting in which there is employed conventional upsweep and downsweep and opposed polarity of signals that are being sent into the earth as seismic signals and in which there is introduced a taper at the common frequency at the common time on the respective upsweep and downsweep signals to reduce the most significant part of the correlation noise, yet provide the advantages of each of the methods of using opposite phase polarity, to cancel and using opposite upsweep and downsweep to achieve reduction in the noise experienced, as well as the reduction of the most significant part of the correlation noise that distorts the desired zero-phase Klauder wavelet.
