Abstract
An improved seismic array and method of seismic exploration are provided which have the capability to supply data to separate recording stations simultaneously. The seismic array has a plurality of seismic detector connection points, and a seismic detector is located at each seismic detector connection point. The outputs of the seismic detectors are electrically isolated from each other, and weighting may be applied to the output of each seismic detector in the array. Two signal-carrying media are also provided in the array, and the weighted outputs of the seismic detectors are conveyed to the first end of the array over one signal-carrying medium and to the second end of the array over the second signal-carrying medium. A Chebychev weighted array is achieved by a proper selection of weighting.
