For low-amplitude events in field data, an AGC could be applied to the
data before filter estimation to help ensure that low amplitude events
are given equal attention in the SPF estimation. In practice, the
prestack 3D traces could be described in 5D space (

source and receiver coordinates. We can extract 3D seismic gathers
from 5D space and use

SPF to interpolate the prestack 3D
traces. Considering the spatial similarity of seismic events, it is
recommended to implement the proposed method in the
cmp-cmpline-offset-azimuth domain. Theoretically, any two spatial
dimensions can be extracted from four spatial dimensions for
interpolation; however, the accuracy of interpolated result depends on
the number of missing traces and complexity in the 3D seismic gathers.
