IMPROVED VIBRATORY SIGNAL SWEEP SEISMIC PROSPECTING METHOD AND APPARATUS Abstract Disclosed are a method and apparatus for vibratory seismic prospecting in which a vibratory signal sweep is produced by a vibrating apparatus in accordance with a power spectrum function S(f), which is proportional to a noise component function n(f) and a subsurface signal amplitude attenuation function B(f) for an area to be surveyed, to thereby produce reflection signals having an improved signal-to-noise ratio.
