Deconvolution the method of characteristics of an unknown source of unknown waveform - data.

摘要

A method for the determination and deconvolution of the signature of an unknown, non-impulsive source signal. The method supposes that an array of receivers is positioned at the earth's surface to detect and record the seismic signals resulting from the interaction of the source with the earth's subsurface. The traces of data recorded are time-shifted by an amount determined by a coherency analysis of the data. The signal is estimated from the time-shifted data with a weighting factor applied at each trace. A deconvolution filter is determined from the estimate and is weighted at each frequency according to the strength of the source at that frequency. The filter is then applied to the time-shifted data.
