1. A method for reconstructing a seismic wavefield, comprising:

  • receiving data over one or more channels of a plurality of channels from a plurality of stations, wherein;

    the data are recorded by a plurality of seismic receivers and represent measurements of properties of the seismic wavefield;

    each station of the plurality of stations comprises a region in space including one or more seismic receivers of the plurality of seismic receivers;

    each channel of the plurality of channels either measures a property of the seismic wavefield or a property of the seismic wavefield after the seismic wavefield has undergone a known transformation; and

    at least one channel of the plurality of channels is derived as a function of one or more other channels of the plurality of channels; and

    using a processor based machine to process the data to;

    model the seismic wavefield as a sum of basis functions;

    apply to the basis functions forward transformations describing the measurements received over the one or more channels of the plurality of channels; and

    determine optimum basis functions based at least in part on the measurements.
