A computer-aided method for providing a de-aliased output data set dL(t,xL,yL) from a spatially aliased, three-dimensional, input data set of known seismic signals, a(t,x,y), where L is an interpolator. The known data set is zero-padded by L. The zero-padded data set is zero-masked. The zero-padded data set is divided by a zero-padded, zero-masked data set to provide an interpolation operator HL. L-1 zero traces are interleaved between the known traces of data set a(t,x,y) to provide a zero-inserted data set cL((t,xL,yL) whose transform is CL(m,kxL,kyL). The product of (HL) with (CL) is (DL) which is inverse-transformed to provide the desired de-aliased data set dL(t,xL,yL). |
