Seismic system and method
This patent describes aeismic apparatus for providing an enhanced seismic signal comprising: a plurality of seismic detector means for detecting vibrations of the earth surface and providing a corresponding plurality of seismic signals representative of the detected vibrations, multiplexing means for multiplexing the seismic signals from the seismic detector means to provide a multiplexed signal, memory means receiving the multiplexed signals for separating and storing portions of the multiplexed signal according to the detector means of origin so that each stored portion is in effect a sample of a seismic signal from a detector means, means for deriving from the stored samples a statistical reference for the seismic signals from the plurality of detector means, means for discarding outlying samples from the stored samples in accordance with the statistical reference, means for combining the remaining samples in a predetermined manner to provide an enhanced seismic signal, and means connected to the discarding means for determining whether or not a statistical significant deviation exists between the rejection rates of the seismic detector means.
