Abstract
An arrangement for conducting a seismic survey and methods for operating a vibrator array in a seismic survey. A signal source coupled to an array of vibrators drives the vibrators with a set of signals to generate seismic signals into a survey area. Each of the signals of the set has an autocorrelation function and a cross correlation function with the other signals of the set that decays faster with time than reflections of the seismic signals from the survey area. One such set of signals includes a linear FM sweep phase-modulated by a maximal-length sequence code shifted a different number of chips for each signal.
