Abstract
Individual seismic source units of a surface array activated simultaneously for cumulative reinforcement may initiate seismic waves at slightly different times despite efforts at synchronization. These variations are measured and used to compute an inverse operator which is applied to the summed uncorrected seismic recording so as to undo the distortion they produce.
