The Impact of the Field Array on Temporal Bandwidth of Land Seismic Data and Its Mitigation in Processing

The field array is the group of seismic sensors connected to a single recording channel. The impact of field arrays on the spatial bandwidth of the recorded seismic data is described by the array wavenumber amplitude transfer function. In this paper, I discuss, however the impact of the field array on the temporal bandwidth of the recorded data. A requirement for this is an accurate knowledge of the field array geometry. I also propose a novel technique to correct the corresponding signal amplitude distortions in data processing.
