Abstract
During the last five years, increasing effort has been spent on the design of high-quality, reliable marine seismic sources. In particular, cluster configurations are now widely used in the seismic industry. We have chosen to define a cluster as follows: 'A gun configuration where interaction effects are deliberately used to improve the signature characteristics'. A typical example of the improvement that can be obtained by proper clustering of the guns is shown in Fig. 1. The signal is obtained from a symmetrical two gun cluster, and superimposed on the plot is the corresponding signature resulting from the same configuration when the two guns are not interacting (infinite separation distance).
