This paper describes in seismic exploration wherein seismic sources are activated at spaced locations along a line of exploration and the amplitude of reflections are recorded as a function of time along the line to produce a series of seismic traces, the series of seismic traces including at least one null trace, a method of restoring seismic data for at least one null trace. It comprises the steps of: producing a frequency-wave number transform for the seismic traces and the null trace; filtering the frequency-wave number transform to retain only spatially coherent events; producing a distance-time representation for the filtered frequency-wave number transform; selecting a filtered trace of the produced distance-time representation which corresponds to the null trace; and substituting the selected filtered trace for the null trace to produce a restored seismic record.
