Abstract

In wavefield signal apparition, acquisition with periodic variations in source activation parameters shifts all or part of a signal cone out to, e.g., the Nyquist wavenumber, enabling perfect separation of simultaneous-source (sim-source) data below a certain temporal frequency. Cyclic convolution in the spatial frequency domain is used to generalise the signal apparition concept to the case of aperiodic variations in the source activation parameters. The separation is formulated as a leastsquares reconstruction in the frequency-wavenumber (f k) domain. The methodology is used in combination with normal moveout correction to de-alias the sim-source separation and enables shooting on position in sim-source acquisition.
