Abstract

The method of acquiring seismic data comprises: allocating respective binary sequences to a plurality of seismic sources (30); emitting seismic waves into a medium during an acquisition time from the plurality of seismic sources, the acquisition time being divided into a plurality of slots and activation of a seismic source in the slots being conditioned by respective bits of the binary sequence allocated to that seismic source; obtaining a seismic signal sensed by a receiver (15) after propagation of the emitted seismic waves in the medium; and combining the seismic signal with the binary sequence allocated to one of the seismic sources.
