Abstract
In some embodiments, apparatus and systems, as well as methods, may operate to enable moving a drill string through a borehole while acquiring data generated by a plurality of receiver sub-arrays included in a drill string. The sub-arrays may be separated by one or more sources of sonic energy, as well as by a non-aliased receiver spacing distance, a distance associated with a selected aperture of investigation, or a distance associated with a formation slowness. The sonic energy may be received by the sub-arrays at a plurality of stations. Data may be collected at a telemetry receiver.
