ABSTRACT:
A method and device are provided for determining the remote emission signature of a seismic emission array. Interactions make the signatures of the different sources different from those that they have separately. To overcome this difficulty, a catalogue is drawn up of the signatures of the sources actuated separately, as a function of parameters such as the immersion depth for example. Then, during combined use of the sources, the value of the parameters is measured and the signatures are selected from the catalogue which each of the sources would have separately if the parameters had the same values as those which are measured. The overall remote signature of the device is obtained by combining the selected signatures.
