Claim 20:
21. A computing device for controlling a multi-source and a hexa-source to acquire first and second seismic datasets to explore a subsurface with a shallow target resolution and with a deep target penetration, the computing device comprising:
an interface configured to receive a number n of source arrays of the multi-source and to receive a number m of sub-arrays for each of the n source arrays, each sub-array having a plurality of source elements; and
a processor connected to the interface and configured to,
apply a distance D between any two adjacent source arrays of the multi-source,
select source elements from at least six different sub-arrays to create the hexa- source,
calculate and apply a distance d between any two adjacent sub-arrays of a same source array among the n source arrays so that first bins and second bins associated with the first and second seismic datasets, respectively, are interleaved, and
fire the multi-source to acquire the first seismic dataset, and fire the hexa-source to acquire the second seismic dataset,
wherein the first bins and the second bins are defined on a surface of the subsurface and include reflection points associated with traces of the first and the second seismic dataset, respectively.
