INSTANTANEOUS FREQUENCY MODULATION ACQUISITION SCHEME FOR SEISMIC SOURCES

摘要

Computing device, computer software and methods for generating sweep signals corresponding to plural sources that generate seismic waves. The method includes selecting (502) a nominal sweep signal (S0); applying (512) a perturbation (P) to the nominal sweep signal (S0); and calculating (518) the sweep signals (Sn) by varying the perturbation (P), each sweep signal corresponding to a seismic source.
