On land, this new method can image targets in complex geological areas that have remained indistinct or invisible until now, in spite of considerable field and processing effort. It can provide cost-effective multicomponent seismic. Although all recording systems are potentially single-sensor systems, problems with signal/noise ratios (SNR's) have made it impractical to replace a conventional analog array with a single geophone. Several single sensors are required for ground-roll suppression, and no recording system has had the capacity to record enough data for the method to be commercial. Furthermore, individual-geophone outputs would have been summed for processing purposes without any preprocessing applied to the array elements. To perform preprocessing, the output of each geophone must be measured and recorded.
