Abstract
A method of processing data sequences obtained at substantially the same time at locations spatially separated from one another is disclosed. A sequence indicative of a measure of spread of the data sequences or of selected data sequences is determined. A common signal data sequence may also be determined from the (selected) data sequences. The measure of spread of the data sequences is preferably normalized, for example relative to the absolute value of the common signal data sequence. The measure of spread is a measure of the noise to signal ratio in the initially-obtained data sequences. It may be used to control the parameters of other processing steps performed on the data sequences. Alternatively or additionally, the measure of spread may be output, for example for monitoring by an observer. The method can be applied to the processing of seismic data obtained using a single sensor seismic data acquisition system.
