METHOD OF DETERMINING THE SIGNATURES OF ARRAYS OF MARINE SEISMIC SOURCES, AND OF ACCUMULATING DATA FOR USE IN SUCH METHODS

摘要

In order to determine the signature of an array of n seismic sources 21 to 27, for instance marine seismic sources in the form of air guns, the array is actuated and the emitted pressure wave is measured at n independent points whose positions will respect to the array are known by hydrophones 31 to 37. The measurements are processed to produce n equivalent signatures of the n sources taking into account the interactions therebetween. The signature of the array is then determined merely by superposing the n equivalent signatures.
