1. A method comprising:
receiving seismic survey data of a subsurface environment from a seismic survey that comprises a source arrangement of sources that is spatially denser than a receiver arrangement of receivers;
processing the seismic survey data by performing interpolation across the receivers using the principle of reciprocity to generate processed seismic survey data, wherein the processed seismic survey data includes interpolated seismic survey data;
deriving priors from non-aliased low-frequency spectrum of the interpolated seismic survey data using the principle of reciprocity;
distinguishing between aliased and true events in the processed seismic survey data based at least partially on the priors; and
generating an image of at least a portion of the subsurface environment using the true events in the processed seismic survey data.
